Sort the subnodes of the soc node to improve maintainability.
The sort key is the address on the bus with instances of the same
IP block grouped together and sorted alphabetically.
Minor whitespace and line-wrapping changes are also made
to match the formatting of R-Car Gen2 SoCs.
This patch should not introduce any functional change.

Add soc node to represent the bus and move all nodes with a base address
into this node. This is consistent with handling of R-Car Gen3, RZ/G1, and
R-Car V2H (R8A77920) SoCs upstream. It is intended to migrate other R-Car
Gen2 SoCs to this scheme.
The ordering is derived from simply moving each node with an address up to
before any nodes without a base address that occur before the soc node. To
improve maintainability follow-up patches will sort subnodes of both the
new soc node and the root node.

Reduce size of thermal registers in DT for r8a7793 (R-Car M3-N) SoC.
According to the "User's Manual: Hardware" v2.00 the registers at base
0xe61f0000 extend to an offset of 0x10, rather than 0x14 which is the case
on the r8a73a4 (R-Mobile APE6).
This should not have any runtime affect as mapping granularity is PAGE_SIZE.

except, again, POLLFREE and POLL_BUSY_LOOP.
With this, we finally get to the promised end result:
- POLL{IN,OUT,...} are plain integers and *not* in __poll_t, so any
stray instances of ->poll() still using those will be caught by
sparse.
- eventpoll.c and select.c warning-free wrt __poll_t
- no more kernel-side definitions of POLL... - userland ones are
visible through the entire kernel (and used pretty much only for
mangle/demangle)
- same behavior as after the first series (i.e. sparc et.al. epoll(2)
working correctly).

This is the mindless scripted replacement of kernel use of POLL*
variables as described by Al, done by this script:
for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do
L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'`
for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done
done
with de-mangling cleanups yet to come.
NOTE! On almost all architectures, the EPOLL* constants have the same
values as the POLL* constants do. But they keyword here is "almost".
For various bad reasons they aren't the same, and epoll() doesn't
actually work quite correctly in some cases due to this on Sparc et al.
The next patch from Al will sort out the final differences, and we
should be all done.

Pull more poll annotation updates from Al Viro:
"This is preparation to solving the problems you've mentioned in the
original poll series.
After this series, the kernel is ready for running
for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do
L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'`
for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done
done
as a for bulk search-and-replace.
After that, the kernel is ready to apply the patch to unify
{de,}mangle_poll(), and then get rid of kernel-side POLL... uses
entirely, and we should be all done with that stuff.
Basically, that's what you suggested wrt KPOLL..., except that we can
use EPOLL... instead - they already are arch-independent (and equal to
what is currently kernel-side POLL...).
After the preparations (in this series) switch to returning EPOLL...
from ->poll() instances is completely mechanical and kernel-side
POLL... can go away. The last step (killing kernel-side POLL... and
unifying {de,}mangle_poll() has to be done after the
search-and-replace job, since we need userland-side POLL... for
unified {de,}mangle_poll(), thus the cherry-pick at the last step.
After that we will have:
- POLL{IN,OUT,...} *not* in __poll_t, so any stray instances of
->poll() still using those will be caught by sparse.
- eventpoll.c and select.c warning-free wrt __poll_t
- no more kernel-side definitions of POLL... - userland ones are

Improve the DTS files by removing all the leading "0x" and zeros to fix the
following dtc warnings:
Warning (unit_address_format): Node /XXX unit name should not have leading "0x"
and
Warning (unit_address_format): Node /XXX unit name should not have leading 0s
Converted using the following command:
find . -type f \( -iname *.dts -o -iname *.dtsi \) -exec sed -E -i -e "s/@0x([0-9a-fA-F\.]+)\s?\{/@\L\1 \{/g" -e "s/@0+([0-9a-fA-F\.]+)\s?\{/@\L\1 \{/g" {} +
For simplicity, two sed expressions were used to solve each warnings separately.
To make the regex expression more robust a few other issues were resolved,
namely setting unit-address to lower case, and adding a whitespace before the
the opening curly brace:
