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.

+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.
