Be more specific in the naming, and follow the existing function naming
pattern of vlv_iosf_sb_*() in the file.

The VLV/CHV IOSF sideband is unrelated to pcode. It's just confusing to
piggyback on the same mutex. Add a dedicated lock with init and cleanup
functions.

vlv_dpio_read() and vlv_dpio_write() really operate on the phy, not
pipe. Passing the pipe instead of the phy as parameter is supposed to be
a convenience, but when the caller has the phy, it becomes an
inconvenience. See e.g. chv_dpio_cmn_power_well_enable() and
assert_chv_phy_powergate().
Figure out the phy in the callers, and pass phy to the dpio functions.

Add a dedicated file vlv_sideband_reg.h for the VLV/CHV sideband
registers. The sideband registers macros are needed by the same files
that need vlv_sideband.h, so include the definitions from there.

The VLV/CHV sideband code is pretty distinct from the rest of the
sideband code. Split it out to new vlv_sideband.[ch].
Pure code movement with relevant #include changes, and a tiny checkpatch
fix on top.
