Add changes to configure register writes in the event
log dump. The register writes can be enabled in the dump
through the debug_fs command.

Setting a lower load can make the regulator enter into LPM. Now the
lower load was set before the regulator disable, there's a risk here.
The regulator has been LPM, while it was not disable, if the cosumer
has a higher current needed than LPM at this time, that will lead OCP
on this regulator. The right operation for a regulator enable/disable
should be:
1. regulator_set_voltage(vreg, active_min_uV, active_max_uV) and
regulator_set_load(vreg, active_load_uA); in either order
2. regulator_enable()
3. regulator_disable()
4. regulator_set_voltage(vreg, inactive_min_uV, inactive_max_uV)
and regulator_set_load(vreg, inactive_load_uA); in either order

Parse the display peripheral related SPMI SID/Peripheral
mask from device-tree and get the dynamic register range
of these peripherals using the SPMI API. These registers
are appended to the list of display IO ranges that is
lent from HLOS to trusted VM during trusted UI. This would
help in adding restrictions for SPMI registers on HLOS during
the trusted UI use case along with validation of the register
ranges in trusted VM.

When the TUI use case starts, HLOS prepares for sharing the HW
by collecting the register io spaces and IRQ lines from all the
participating subdrivers before the switch. This change
adds necessary hook in the VM event framework, so that
subdrivers can provide their callback functions while
registering for events. It also adds necessary helpers
in the sde io util to parse and populate the IO memory
region that needs to be shared.

This change sets the regulator voltage to zero for all
those regulators which support voltage scaling before
disabling the regulator. Failing to do so causes the regulator
vote to set to the last min value specified in the previous
set voltage call.
Additionally modified the config regulator api and renamed to
get regulator because of the above change.
