Simon Glass 8e2922e357 x86: spi: Add a way to access the SPI mapping via registers ...

At present the PCI BDF (bus/device/function) is needed to access the SPI
mapping, since the registers are at BAR0. This doesn't work when PCI
auto-config has not been done yet, since BARs are unassigned.

Add another way to find the mapping, using the MMIO base, if the caller
knows this.

Also add a missing function comment.
