arm64: dts: rockchip: Increase maximum frequency of SPI flash for ROCK Pi 4A/B/C
The ROCK Pi 4A/B/C boards come with a 32 Mbit SPI NOR flash chip (XTX
Technology Limited XT25F32) with a maximum clock frequency of 108 MHz.
Use this value for the device node's spi-max-frequency property.
This patch has been tested on ROCK Pi 4A.
