mmc: tegra2: fix HC version register offset
The ADMA address register has provision to support hardware with 64-bit
physical addressing. By the way, on Tegra2 a long is 32 bits, so we need
to reserve another 32-bit word to ensure that the next registers are at
the right place.
BUG=none
TEST=run U-Boot on Qemu and check that the host controller version is
read at offset 0xfe and no longer at 0xfa
