device/main/linux-postmarketos-allwinner: enable CONFIG_ARM_SUN8I_A33_MBUS_DEVFREQ and devfreq governors
This enables the DRAM frequency stats driver that can be useful for debugging issues with the PinePhone. This came up in a discussion in #pinephone on IRC where megi was helping a pmos user with idle power draw issues.
This also enables the performance, powersave and userspace devfreq governors.
