Subject: [PATCH 0/4] thermal: qcom-spmi-temp-alarm: Add support for new TEMP_ALARM subtypes

Add support in the qcom-spmi-temp-alarm driver for the new PMIC
TEMP_ALARM peripheral subtypes: GEN2 rev 2 and LITE. The GEN2 rev 2
subtype provides greater flexibility in temperature threshold
specification by using an independent register value to configure
each of the three thresholds. The LITE subtype utilizes a simplified
set of control registers to configure two thresholds: warning and
shutdown. While at it refactor the qcom-spmi-temp-alarm driver to limit
code reuse and if/else statements when deciphering between TEMP_ALARM 
peripheral subtypes. 

Also add support to avoid a potential issue on certain versions of
the TEMP_ALARM GEN2 subtype when automatic stage 2 partial shutdown
is disabled.

This patch series is a continuation of older series from 7/2024
(https://lore.kernel.org/all/20240729231259.2122976-1-quic_amelende@quicinc.com/)
but current series has been reworked to address the change in thermal framework to
update .set_trip_temp() callback function variables
(https://lore.kernel.org/all/8392906.T7Z3S40VBb@rjwysocki.net/)
