By now the code to only have a single page table level with 64k page
size and 42 bit address space is no longer used by any board in tree,
so we can safely remove it.
To clean up code, move the layerscape mmu code to the new defines,
removing redundant field definitions.

Now that we have nice table driven page table creating code that gives
us everything we need, move to that.

The size allocation for SPL is increased in all cases to match the
already-expanded value used on Tegra124. This is both for general
consistency, and because the seaboard build trips over the limit already
when using one of the ARM compilers packaged with 14.04. For the record,
when building Seaboard:
arm-linux-gnueabi- SPL is too big by 0x36 bytes
arm-linux-gnueabihf- SPL fits by 0x2a bytes
arm-none-eabi- SPL fits by 0xa bytes
(Those figures are from builds with the expanded SPL size allocation,
relative to the non-expanded SPL size limit; they're better by about
6 bytes in the more constrained build.)

The new value is the most likely value where the kernel wants to end up
at run-time. Selecting this value as the load address likely avoids the
need to copy the kernel image from the actual load address to the desired
load address. Note that this isn't guaranteed since the kernel may wish
to run at an arbitrary location. In that case, U-Boot will still relocate
the image according to its wishes; this change is a performance
optimization, not a hard-coding of the final image location.

U-boot is responsible for enabling the GPU DT node after all necessary
configuration (VPR setup for T124) is performed. In order to be able to
check whether this configuration has been performed right before booting
the kernel, make it happen during board_init().
Also move VPR configuration into the more generic gpu.c file, which will
also host other GPU-related functions, and let boards specify
individually whether they need VPR setup or not.

Based on Venice2, incorporates Stephen Warren's
latest P2571 pinmux table.
With Thierry Reding's 64-bit build fixes, this
will build and and boot in 64-bit on my P2571
(when used with a 32-bit AVP loader).
