As newer GPU families are added it makes less sense to maintain a
"generic" version functions for older families. Move adreno_submit()
and get_rptr() into the target specific code for a2xx, a3xx and a4xx.
Add a parameter to adreno_flush to pass the target specific WPTR register
instead of relying on the generic register.
All of this gets rid of the last of the REG_ADRENO offsets so remove all
all the register definitions and infrastructure.

Disable the RPTR shadow across all targets. It will be selectively
re-enabled later for targets that need it.

msm_gem_address_space_create() changed to take a start/length instead
of a start/end for the iova space but all of the callers were just
cut and pasted from the old usage. Most of the mistakes have been fixed
up so just catch up the rest.

Refactor how address space initialization works. Instead of having the
address space function create the MMU object (and thus require separate but
equal functions for gpummu and iommu) use a single function and pass the
MMU struct in. Make the generic code cleaner by using target specific
functions to create the address space so a2xx can do its own thing in its
own space. For all the other targets use a generic helper to initialize
IOMMU but leave the door open for newer targets to use customization
if they need it.

A2XX has its own very simple MMU.
Added a msm_use_mmu() function because we can't rely on iommu_present to
decide to use MMU or not.
