[RFC PATCH v2 39/48] add a function to check if an address is in RAM memory

[Sughosh Ganu]

Add a function to check if a given address falls within the RAM
address used by U-Boot. This will be used to notify other modules if
the address gets allocated, so as to not get re-allocated by some
other module.
