mb/cedarisland_crb: rework GPIOs configuration using macros
This format of PCH GPIOs configuration, unlike the raw DW0 and DW1 registers values from the inteltool dump, is more understandable and makes the code much cleaner. The gpio.h file with PAD_CFG macros was automatically generated using the util/intelp2m [1] utility: ./intelp2m -p lbg -file cedarisland/vendorbios/inteltool_gpio.log According to the documentation [2], the Host Software Pad Ownership register only affects the pads that are configured as input. The intelp2m utility takes this into account when converting macros and ignores bits from this register for the corresponding pads.
