Update GPIO config based on review of latest schematics:

- LAN/WLAN reset lines are NC
- SDIO lines configured via GPP_G0-G7
- DMIC lines are wired directly to codec, not PCH, so GPP_D17-20
  are set to NC
- Pads GPP_H0-H3 are configured for I2S2
- Pads GP_H7-H9 are straps for board revision, so treated as GPI
- CPU_C10_GATE# is NC
- PWRBTN# does not need an internal pull-up
- GPP_C20-23 are configured for M.2 UART
- SATAXPCIE1/2 and EC SCI/SMI lines do not need internal pull ups
- GPP_C6/C7 set to I2C1 for future use
- GPP_E15 changed from SCI to SMI, edge triggered
