mb/system76/lemp9: gpio: configure unused pads
There are pads being unused for various reasons:
a) missing board support (DeepSx: SUSWARN#)
b) unneeded feature ID pins
- currently no known device models without keyboard backlight
- currently no known device models without TPM
c) BOARD_ID (L140CU/L140ZU) is fixed and known at build time
d) DDR_TYPE_*: there is only one known ram model
e) strap-only pads
f) unconnected pads
Configure them as NC with appropriate pull-up if no external pull exists.
The latter was checked by schematics and looking at the board.
When any of the unused ID pins is needed in the future, they can be
reactivated easily (configure as GPI).
Further, convert from use of legacy macro PAD_CFG_NC to PAD_NC.
