zero-sugar dts: (max77818) en. FGCC/dis. SAFEOUT reg./en. GPIO based chg status 

Tune JEITA configuration (mainly) and other settings, FGCC mode seems to work
as expected.

Disable regulator definition for SAFEOUT signals, thus leave the SAFEOUT
config as default, following CHGIN charger presence.

Add required pinctrl config for GPIO based connection status read from charger
device when this is offline from the I2C bus (100K PU).
