Subject: [PATCH V3 1/4] regulator: dt-bindings: Add pm8008 regulator bindings

Add bindings for pm8008 pmic regulators.

Signed-off-by: Satya Priya <quic_c_skakit@...cinc.com>

Changes in V2:
 - Moved this patch before "mfd: pm8008: Add pm8008 regulator node" to
   resolve dtschema errors. Removed regulator-min-microvolt and 
   regulator-max-microvolt properties.

Changes in V3:
 - As per Rob's comments added standard unit suffix for mindropout property,
   added blank lines where required and added description for reg property.

 - As per Stephen's comments, changed the qcom,min-dropout-voltage to standard
   property regulator-min-dropout-voltage-microvolt.
