arm64: dts: rockchip: Add NOR flash to ODROID-M1

Browse Source 
Enable the Rockchip Serial Flash Controller for the ODROID-M1 and add
the corresponding SPI NOR flash entry. The SFC is used in dual I/O mode
and not quad I/O mode, as the FSPI_D2 pin is shared with the EMMC_RSTn
pin.

The partitions addresses and sizes are taken from the ODROID-M1
Partition Table page on the ODROID wiki.
