For MMP platform have not only one bank, so now named the audio sram 
bank as "asram", and another sram bank as "isram" which is used by 
video/secure processor/pm.
If other modules want to use the sram, just use the name string to
get the gen pool handler, and then just call genalloc APIs.

I just wander if maintain the name in genalloc, then the name string
we should maintain in the pool's structure or chunk's structure?
