On VADC_HC peripheral the ADC code can extend beyond
0-0x4000 range if the input is below 0V or if the
offset and gain error needs to be calibrated out.
Clamp the values for cases where the code represents
the value below 0V.

Add support to scale reverse thresholds on VADC_TM refresh
peripheral for voltage measurements such as vbatt, vph_pwr,
thermistor channels, PMIC die temperature.
VADC_TM refresh uses one interrupt for high and low threshold
notification. Update the sequence to check the respective
sensors status for high/low threshold crossing for the VADC_TM
refresh and notify the clients on a threshold crossing.

Add option to select whether a fresh calibration
needs to be performed when performing the channel measurement.
If the property is not present the default value of
using calibration measurement collected from a timer
will be used. For most cases using a measurement collected
from a timer interval should suffice and the default value
can be used.

The BTM (Battery temperature module) peripheral driver
on the PMIC (Power management IC) supports threshold
monitoring and notifies clients when thresholds are crossed.
PMCOBALT supports refreshed BTM peripheral register interface
and the driver uses compatible property qpnp-adc-tm-hc to
distinguish using the refreshed peripheral. The external
client interface with the driver remains the same. Updates
include handling the interrupt when the thresholds are
crossed,programming the threholds and configuring
the hardware based on the refreshed design.
BTM peripheral needs the VADC_HC peripheral to compute the
gain/offset that are used to reverse compute the threhold
values to ADC code. Some of the reverse computation API's
such as calculating thermistor thresholds require the
gain and offset values before computing the ADC code to
be programmed. This requires modification to the existing
calibration API in the VADC_HC driver to calculate
the reference calibration points and store these values
for clients to use in the reverse computation

The TYPE for a PMIC chip is always 0x51. There is no need to define it
for each PMIC chip.
Also the SUBTYPE of a PMIC chip doesn't change with versions. Have a
single definition of the SUBTYPE per PMIC chip.
Also, the driver uses integer indexes to get to the pmic name, instead
use the SUBTYPE to index in the pmic names array.

Change to using upstream spmi bus architecture. All the spmi devices,
marked by spmi-dev-container, become platform devices.
spmi-slave-container devices become spmi_devices each representing
a slave. The read/write functions use regmap api's instead of calls to
spmi_ext_register_read/write() implemented by the spmi bus. This
regmap is instantiated per slave.
The spmi bus helper functions like spmi_get_irq get changed to their
platform bus equivalents.
Change Kconfig files include
* Remove dependence on OF_SPMI, MSM_QPNP_INT
* There were few places where an earlier commit
dcc2aedc80746acee589e4b47d3e6adf5d3ec253
missed adding dependence on SPMI along with MSM_SPMI.
Fix them.
* Add depends on ARCH_MSM. ARCH_MSM is used for internal builds.
Change the nodes in DTSI files to confirm to the modified drivers.
Update their binding docs to drop spmi-dev-container and
spmi-slave-container;
Finally update defconfig to use upstream SPMI.
