dev: pmic: Move the old-gen vibrator to the common pm8x41 file

QM215 uses the msm8952 platform configuration. The PMIC supported
on QM215 is PM8916 which uses the old-gen vibrator. To support
both the vibrators (PM8916 and PMI8950/37) add logic which
detects the PMIC type and calls into the right vibrator function.
