Made GPIO module ROMmable

Detail:
  Changed to use CModule shared makefile.
  No need to call __RelocCode when targeting ROM (relocation is done at
  ROM link time instead). In fact, the linker doesn't create __RelocCode
  in this case, so link fails unless it's removed.
Admin:
  Tested on Raspberry Pi

Version 0.51. Tagged as 'GPIO-0_51'
