power: qpnp-qnovo5: Add driver to support Qnovo5

Qnovo5 is a PBS based pulse charging engine which has different
pulse train pattern and register mapping with the legacy Qnovo
module. Add the driver to export the registers of the hardware
module and the parameters of the charging status to allow the
userspace code to diagnose and control the charging phase.
