ARM: 6625/1: use memblock memory regions for "System RAM" I/O resources
Do not use memory bank info to request the "system ram" resources as
they do not track holes created by memblock_remove inside
machine's reserve callback. If the removed memory is passed as
platform_device's ioresource, then drivers that call
request_mem_region would fail due to a conflict with the incorrectly
configured system ram resource.
Instead, iterate through the regions of memblock.memory and add
those as "System RAM" resources.
