pmic: Convert pm8916 driver to a generic Qcom PMIC driver
Since both pm8916.c and pm8916_gpio.c are already supporting multiple
Qcom SoCs, it makes sense to rename these drivers to pmic_qcom.c and
qcom_pmic_gpio.c respectively. Also, these driver can be extended to
support additional functionality if required for other Qcom SoCs.
Along with this import latest DT binding: qcom,spmi-pmic.txt from Linux
kernel and thereby remove pm8916.txt.

Default name for GPIO bank is "pm8916".
- Power and reset buttons are placed in "pm8916_key" bank and
+ Power and reset buttons are placed in "pwkey_qcom" bank and
have gpio numbers 0 and 1 respectively.
