IRQ driver can be used by codecs that do not use the core driver.
Refactor the drivers so that codec drivers that are not children
of the core driver can also request/access the interrupt routines
provided by the IRQ driver.

During subsystem restart, it's possible codec's upstream irq is disabled
if irq handler tried to access codec register when it's inaccessible.
Reinitialize codec irq handler after subsystem restart to be able to
bring codec interrupts back to work again.

1. Add configurable parameters to
- enable/disable fcc learning
- minimum soc to start FCC learning
- minimum ocv (pc) to start FCC learning
- minimum cycles to update fcc vs temp. table
2. New FCC is calculated using the cc count-
FCC_NEW = (cc_end - cc_start) / (soc2 - soc1)
cc_end = CC count when charing ends
cc_start = CC count when charging starts
soc1, soc2 = starting and ending SOC_rbatt value
3. Add a new sysfs entries to update the learnt fcc values
to userspace. These values are restored back on

Currently wcd9320 driver assumes micbias 2 is dedicated to headset and ANC
microphones on headset. Allow different microphones share the micbias 2 to
support hardware that have shared micbias configuration.
If micbias 2 is shared by mic biases other than headset mic, MBHC's ext
cable feature will be compromized and also headset removal can make more
pop noise. If hardware has dedicated micbias 2 for headset, it's
recommanded to disable this feature.

The wcd9320 and wcd9306 codec have additional interrupt bits which are not
currently masked. Therefore it's possible those interrupts assert and
never be cleared by driver. Mask additional interrupt mask bits in order
to prevent irq flooding.
Additionally enhance irq handler to clear unhandled nested irq so even
buggy driver cannot make irq flooding.

There are situations when the corrections can cause linearity issues.
Provide a scheme to limit the corrections via a configurable parameters.
The corrections were introduced to prevent battery dipping below UVLO.
If the battery were in the flat portion of the SOC curve a small error
in OCV measurement could drift the SOC by a large amount. Corrections
are important if the OCV falls in this range. Hence introduce two
parameters to limit the corrections based on a OCV threshold - one when
it is above 3.8 volts, where corrections could be low and the other
when the OCV is lower and 3.8 (flat portion) where corrections should be
high.
Also there are instances when the SOC appears stuck at 1% for a long
time. This is because the algorithm doesn't allow the soc to drop to 0%
if the estimated soc is high. Provide a configurable level for the
estimated SOC below which, the calculated soc can go to 0%.

When MBHC detects new plug type, MBHC driver turns on vddio switch in order
to check if plug is fully inserted. But utilizing vddio switch can lead to
plug type detection failure when plugged headset behaves differently
between with and without vddio switch.
The HPHL status register can replace the vddio switch so driver can check
if plug is fully inserted by reading the HPHL status register. Hence
replace vddio switch with HPHL status register.
