Change the BiosRam read/write functions to use the fixed MMIO range at
0xfed80500. This is faster than two accesses per byte when using I/O
0xcd4/0xcd5.
Note that BiosRam may only be accessed byte-by-byte. It does not decode
normally.

forcing another parameter of struct device so one can do the lookup.
This works for Intel-based systems since the struct device was needed
to program the BAR, etc. However, from an API standpoint, it just
complicates matters by needing to obtain the struct device. The SoC
already has knowlege of its own devices so it can get the config
itself by bus number. Therefore, remove that contraint from the API.
