[PATCH 12/12] ARM: rpc: rename RAM_SIZE macro

The RAM_SIZE macro in mach/hardware.h conflicts with macros of
the same name in multiple drivers, leading to annoying build warnings:

In file included from drivers/net/ethernet/cirrus/cs89x0.c:79:0:
drivers/net/ethernet/cirrus/cs89x0.h:324:0: error: "RAM_SIZE" redefined [-Werror]
#define RAM_SIZE 0x1000 /* The card has 4k bytes or RAM */
^

from /git/arm-soc/drivers/net/ethernet/cirrus/cs89x0.c:54:
arch/arm/mach-rpc/include/mach/hardware.h:28:0: note: this is the location of the previous definition
#define RAM_SIZE 0x10000000

We don't use RAM_SIZE/RAM_START at all, so we could just remove
them, but it might be nice to leave them for documentation purposes,
so this renames them to RPC_RAM_SIZE/RPC_RAM_START in order to
avoid the build warnings
