According to the 82371FB documentation (82371FB.pdf, 2.3.9. BMIBA-BUS
MASTER INTERFACE BASE ADDRESS REGISTER, April 1997), the register is
32bit wide. To properly reset it to default values, all 32bit need to be
cleared. Bit #0 "Resource Type Indicator (RTE)" needs to be enabled.
The initial change wrote just the lower 8 bit, leaving parts of the "Bus
Master Interface Base Address" address at bit 15:4 unchanged.
Fixes: e6a71ae327 ("Add support for 82371FB (Step A1) and Improved support for 82371SB (Function 1)")
