Daniel Golle 7c468e5e64 mediatek: rename or replace accepted patches
Rename kernel patches accepted upstream to indicate at which version
they have been accepted, replacing downstream variants which what was
accepted upstream. Note that some of them are fixes which will
find their way to older kernel versions as well via linux-stable.
No functional changes.

Subject: [PATCH] arm64: dts: mt7622: declare SPI-NAND present on BPI-R64
The SPI-NOR node in the device tree of the BananaPi R64 has most likely
been copied from the reference board's device tree even though the R64
comes with an SPI-NAND chip rather than SPI-NOR.
Setup the Serial NAND Flash Interface (SNFI) controller, enable
hardware BCH error detection and correction engine and add the SPI-NAND
chip including basic partitions,
