intel/cannonlake_rvp: Clean up GPIO programming

Since we move from cannonlake U DDR 4 platform to cannonlake U LPDDR4
platform, it is also critical to revisit the GPIO settings as they are
different. Remove unused GPIO setting for old platform, and clean up the
native function definition. PAD_CFG_NF can only select NF1,NF2 ..., set
to GPIO mode is illegal.

TEST=Boot up in chromeos successfully.
