ARM: dts: realview: Extend PBX family memory description

All three platforms sharing the later RealView Platform Baseboard memory
map - PBX-A9, PB-A8 and PB11MPCore, provide 512MB of DDR SDRAM on the
baseboard, of which the boot alias at 0x0 maps the first 256MB. Expand
the size of the default memory node to reflect that, and describe the
full memory regions in each board's DTS, but leave those commented by
default to avoid breaking existing bootloaders.

ARM SoC folks: I forgot to send this patch for ARM SoC earlier.
As it is a small change I suggest you just apply it to the ARM
SoC tree as I do not foresee any other RealView work in the near
future. If you think it can go into v4.9 then put it in as a fix,
else just push it to the next merge window.
Robin: sorry for screwing up :(
