rt2x00: Optimize register access in rt2800pci
All register reads/writes in rt2800pci were previously done with
rt2800_register_read/rt2800_register_write. These however indirectly
call rt2x00pci_register_read/rt2x00pci_register_write which adds an
additional overhead of at least one call and several move instructions
to each register access.
Replacing the calls to rt2800_register_read/rt2800_register_write with
direct calls to rt2x00pci_register_read/rt2x00pci_register_write gets
rid of quite a number of instructions in the drivers hotpaths (IRQ
handling and txdone handling).
For consistency replace all references to rt2800_register_read/write
with the rt2x00pci_register_read/write variants.
