ramips/mt7621: enable support for cpuidle
MIPS Coherent Processor Systems (CPS), which include the MT7621 SoC, support
deep sleep idle states and have a specific cpuidle driver for them.
Enable support for it, while also switching from constant timer ticks to the
idle dynticks model, with the TEO governor.
Run-tested on a Redmi AC2100.
