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.)
Fixes: ba52199422 ("tegra124: Expand SPL space by 8KB")
