rt2x00: cleanup patches

Browse source 
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.

Subject: [PATCH] rt2x00: fix rt2800pci hang on ifdown
rt2800pci hangs the system on rt305x SoC devices on ifdown. Work around
this issue by disabling TX DMA prior to restting the TX queue indices.
This patch is not suitable for upstream inclusion but is just meant as
a workaround until a proper solution is implemented.
