Add new GPIO device type & OMAP3 GPIO device ID

Detail:
  hdr/HALDevice - Added GPIO device type in the Comms group, and an ID for a generic OMAP3 GPIO device
  hdr/GPIODevice - Definition of GPIO device structure. Currently only used to store the type and revision of the main board, so the GPIO manager module can tailor its features appropriately.
  Makefile - Export hdr/GPIODevice
Admin:
  Tested on rev A2 BB-xM


Version 5.35, 4.79.2.98.2.42. Tagged as 'Kernel-5_35-4_79_2_98_2_42'
