ARM: mmp: register internal sram bank
MMP2 have the internal sram, this sram can be allocated
for video, power management and secure processor.
Now the sram usage is:
0xd1000000 ~ 0xd101ffff (128KB) : reserved for secure processor
0xd1020000 ~ 0xd1037fff (96KB) : for video and PM
Register the internal sram's second half 96KB buffer,
so that video and PM can dynamically alloc/free from it.
