ichspi: Do not mmap for hwseq

Flash chips >16 MB can't be directly mapped into memory, this usually
results in a failure since the attempted mapping would overlap with PCI
devices.  The mapping isn't needed for these methods.

This change is likely also correct for ICH swseq and possibly others,
these would need to be tested.

Test: Probe and read firmware on 400-series PCH with 16 MB and 32 MB
SPI flash
