dt-bindings: mfd: pm8008: Rework binding

Rework the pm8008 binding, which is currently unused, 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).
