Rework the pm8008 binding by dropping internal details like register
offsets and interrupts and by adding the missing regulator and
temperature alarm properties.

Note that child nodes are still used for pinctrl and regulator
configuration.

Also note that the pinctrl state definition will be extended later and
could eventually also be shared with other PMICs (e.g. by breaking out
bits of qcom,pmic-gpio.yaml).
