rt2x00: cleanup patches
Remove 601-rt2x00-remove-mcu-requests-for-soc.patch as an equivalent patch
is already included in upstream.
Add 601-rt2x00-fix-hang-on-ifdown.patch which is not suitable for upstream
inclusion but fixes a hang on ifdown under some circumstances and thus also
fixes AP mode operation in OpenWRT.
