rt2x00: Fix BUG on rt2800usb when trying to read eFuse EEPROM.
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.
