siemens/mc_apl1: Extend circuit life by clock gating and power gating
The firmware of devices connected to LPC should deassert the LPC CLKRUN#
signal when there is no bus activity on LPC.
Necessary changes:
- Enable LPC CLKRUN#
- Enable LPC PCE (Power Control Enable)
- Enable LPC CCE (Clock Control Enable)
- Remove I/O decoding range on LPC for COM 3
- Disable I/O UART driver
