rt2800: prepare for unification of EEPROM support code
* Factor out common code from rt2800[pci,usb]_validate_eeprom()
to rt2800_validate_eeprom().
* Fix interface specific comment in rt2800[pci,usb]_validate_eeprom().
* Enclose interface specific code in rt2800[pci,usb]_init_eeprom()
with rt2x00_intf_is_[pci,usb]() checks.
