ARM: OMAP5: Align memory used for testing to the power of 2

Browse Source 
get_ram_size checks the given memory range for valid ram,
but expects the size of memory to be aligned to the power
of 2. In case of OMAP5 evm board the memory available is
2GB - 16MB(used for TRAP section) = 2032MB.

So always ensure that the size of memory used for testing is
aligned to the power of 2.
