Add SW support for the vibrator module inside PMI632, PM7250B, PM7325B, PM7550BA.
It is very similar to the vibrator module inside PM8916 which is supported in
pm8xxx-vib driver but just the drive amplitude is controlled with 2 registers,
and the register base offset in each PMIC is different.

Changes in v3:
  1. Refactor the driver to support different type of the vibrators with
    better flexibility by introducing the HW type with corresponding
    register fields definitions.
  2. Add 'qcom,spmi-vib-gen1' and 'qcom,spmi-vib-gen2' compatible
    strings, and add PMI632, PM7250B, PM7325B, PM7550BA as compatbile as
    spmi-vib-gen2.
 
Changes in v2:
  Remove the "pm7550ba-vib" compatible string as it's compatible with pm7325b.
