nvmem: meson-efuse: bindings: add peripheral clock

jbrun3t · gregkh · commit a91ae340ad05 · 2018-12-06T15:45:45.000+01:00
The efuse found in gx SoC requires a peripheral clock to properly operate.
We have been able to work without it until now because the clock was on by
default, and left on by the CCF. Soon, it will not be the case anymore, so
the device needs to claim the clock it needs
