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...)
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....)

Changes since v4:
  - Removed the unnecessary thresh member of the qpnp_tm_chip struct in patch 2/5
  - Updated order of logic to limit acquiring and releasing lock within
    qpnp_tm_init() in patch 3/5
  - Fixed misuse of signed vs unsigned integers in patches 4/5 and 5/5
  - Added Dmitry's reviewed-by tag in patch 5/5
  - link: https://lore.kernel.org/all/20250528235026.4171109-1-anje...
Changes since v3:
  - Updated order of logic and made dig revision a local variable in patch 1/5
  - Updated Locking Logic in patches 3/5, 4/5, 5/5
  - link: https://lore.kernel.org/all/20250320202408.3940777-1-anje...
Changes since v2:
  - Updated function name to include "gen1" in patch 2/5
  - Added Dmitry's reviewed-by tag in patch 2/5
  - link: https://lore.kernel.org/all/20250225192429.2328092-1-anje...
Changes since v1:
  - Remove unnecessary moving of code
  - Added new v2 patch 3/5 add a preparation patch to v1 patch 2/5
  - Updated temp alarm data function names to be consistently named
