[PATCH] Make ram_addr_t 64 bits unconditionally

[Bin Meng]

From: Bin Meng <bin.meng@windriver.com>

Currently machine->ram_size is a ram_addr_t, whose size is 64 bits
if either (a) the host is 64 bits or (b) CONFIG_XEN_BACKEND is
enabled, so it's effectively only 32 bits on 32-bit-not-x86.

commit 4be403c8158e ("Make target_phys_addr_t 64 bits unconditionally")
did the change for target_phys_addr_t which is now hwaddr to be 64 bits
unconditionally. Let's do the same to ram_addr_t.
