Resource: Update to handle resource table area using linker symbol

- Modified to  place memory only if loadSegment is defined
- For new platforms, SYSBIOS will not handle platform memory map.
So the linker command file is external. Only way to get the
start address is using the external linker symbol.
- Added new variable loadSymbol to allow setting the tableptr using
symbol
