Few adc_tm registers have different offsets on PMIC5 compared
to PMIC4. Update logic to account for PMIC5 registers.

TWM (Traditional watch mode) is a low power mode supported
on the BG platform. PMIC is configured differently
while entering into TWM mode.
Add a sysfs node to -
1. Allow the BG daemon to enable/disable TWM mode.
echo 1 > /sys/class/pmic_twm/twm_enable --> Enable TWM mode
echo 0 > /sys/class/pmic_twm/twm_enable --> Clear TWM mode
2. Allow the BG daemon to check the TWM_EXIT state.
cat /sys/class/pmic_twm/twm_exit
Value of "1" indicates exit from TWM state
Also, add a notifier to notify other modules of the TWM enable
configuration.

OLEDB_SPARE_CTL register bit is set by the PBS during the display enable
and is used during the display suspend to trigger the PBS event.
Hence, move clearing of the OLEDB_SPARE_CTL register to regulator disable.
Also enable the force_pd_ctl only for DRAX-A revisions <=2.0.

Update VADC property to obtain the code for the full scale
voltage instead of the number of bits for the ADC. The
full scale code is more useful for scaling code to voltage.
Update the property as an optional property and use default
full scale code of 0x4000 for 1.875V.

'commit 9af69213de64 ("Merge "block: Move bdi_unregister() to
del_gendisk()"")'
Fixed a couple of minor issues to solve checkpatch errors.
- Use const qualifier for qpnp_misc_match_table
- Fixed a block comment
Also, moved the location of qpnp-misc.h from include/linux to
include/linux/qpnp.
