Instead of fiddling with the skb->data pointer and thereby risking
out of bounds accesses, properly reserve the space needed in an
skb for descriptors.

RXWI processing is exactly the same for rt2800pci and rt2800usb, so
make it common code.

The rt2800pci_wait_wpdma_ready and rt2800usb_wait_wpdma_ready functions are
exactly the same, so unify them into rt200lib.

Current tree hits a BUG_ON in rt2x00_regbusy_read, because the eFuse EEPROM
reading code of rt2800lib uses the function without the csr_mutex locked.

Fix this by locking the csr_mutex for the of the EEPROM reading cycly and
using the _lock variants of the register reading and writing functions.

This also introcudes the register_read_lock function pointer in the
rt2800_ops structure.

eFuse EEPROM is used also by USB chips (i.e. RT3070)
so move the needed code from rt2800pci to rt2800lib.
