qpnp-qnovo: IADC/ESR workarounds

When FG IADC measurement period coincides with qnovo discharge pulses
it reads incorrect IADC values. That causes issues with SOC accuracy
and capacity learning amongst others.

The fix to IADC inaccuracy is to set a bit in the FG peripheral while
Qnovo is active.

A side effect of IADC inaccuracy fix is that the ESR measurement goes
haywire. To overcome that, disable ESR when Qnovo is active and force
an esr measurement when its between pulses.

Realize this by setting CHARGE_QNOVO_ENABLE and RESISTANCE property on
the bms psy at appropriate times in the driver.
