sunxi: Remove unneeded patches

In the device tree file the higher offsets of the reset controller are
not used, so this patch supporting higher bits is not needed.
The sunxi architecture switched to the simple reset controller with
kernel 4.19 and then this patch does not apply any more.
The sunxi target in OpenWrt is very close to mainline, so if the device
tree files from the mainline Linux kernel need this the mainline kernel
will get support for this.

-Subject: [PATCH] musb: sunxi: Ignore VBus errors in host-only mode
-
-For some unclear reason sometimes we get VBus errors in host-only mode,
-even though we do not have any vbus-detection then. Ignore these.

-Subject: [PATCH] reset: sunxi: Add Allwinner H3 bus resets
-
-The H3 bus resets have some holes between the registers, so we add
-an of_xlate() function to skip them according to the datasheet.
