This commit increases the SPI bus frequency from 20 to 52 MHz. Reduces boot
time by 2s. Below is a performance comparison.

After:
root@OpenWrt:~# dd if=/dev/mtd1 of=/dev/null bs=10M count=1 status=progress
10485760 bytes (10 MB, 10 MiB) copied, 0.819222 s, 12.8 MB/s

Taken from PR #18752 as each device should be tested individually, so I have
created a separate PR for this.
