rt2x00: Optimize register access in rt2800usb
All register reads/writes in rt2800usb were previously done with rt2800_register_read/rt2800_register_write. These however indirectly call rt2x00usb_register_read/rt2x00usb_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 rt2x00usb_register_read/rt2x00usb_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 rt2x00usb_register_read/write variants. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.
