Proper error handling for ICH/VIA SPI:
Use 16-bit values for bit masks in 16-bit registers.
Check for SPI Cycle In Progress and wait up to 60 ms.
Do not touch reserved bits.
Reduce SPI cycle timeout from 60 s to 60 ms.
Clear transaction errors caused by our own SPI accesses.
Add better debugging in case the hardware misbehaves.
