regulator: qcom_spmi: Add support for PM8004 regulators

This Power IC is used in combination with various PMIC combos,
generally found on boards with MSM8992, MSM8994, MSM8996,
MSM8956, MSM8976 and others, usually at address 0x5 on the SPMI
bus, and its usual usage is to provide power to the GPU and/or
to the CPU clusters (APC0/APC1).
