Introduce enable_flash_ich_fwh_decode()
ICH2 (and C-ICH)/3/4/5 also have FWH_SEL1/2 registers but at
different addresses. In preparation for implementing fwh_idsel
parsing for older ICH chipsets extract the parameter handling
and add variables for the offsets.
While FWH_DEC_EN1 is a 16bit register for ICH6, it is two separate
8bit registers on ICH5 and earlier. Implement all accesses with two
byte instructions instead, to prepare for extended support.
Corresponding to flashrom svn r1746.
