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,
