rt2x00: Driver requiring firmware should select crc algo

The driver should select what CRC algorithm is required
when performing a checksum on the firmware.

rt61pci & rt73usb require crc-itu-t
rt2800pci & rt2800usb require crc-ccitt

Legacy 2800pci/usb driver uses crc-itu-t + bit order reversion,
but that is just inefficient especially since the end result is
the same as a different algorithm which is also available as library. ;)
