[LinuxBIOS] [v2][PATCH] Trivial fixups for i82801xx_lpc

Hello,
Here is a patch with mostly trivial fixups for i82801x_lpc.c. The main  
fixup is the PIRQ Routing Control.

1. These are 8 bit registers not 32.
2. There were PIRQ channels that were disabled. This should not be  
determined here but by irq_tables.c or by acpi_tables.c on a mainboard  
level.

3. The rest of the fixups were trivial.
