qemu/pci: make default_write_config use mask table
Change much of hw/pci to use symbolic constants and a table-driven
design: add a mask table with writable bits set and readonly bits unset.
Detect change by comparing original and new registers.
This makes it easy to support capabilities where read-only/writeable
bit layout differs between devices, depending on capabilities present.
As a result, writing a single byte in BAR registers now works as
it should. Writing to upper limit registers in the bridge
also works as it should. Code is also shorter.
