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.
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.
Changes since v2 [1]:
* Added missing header <linux/bitfield.h> in the third patch
Changes since v1 [2]:
* Updated the thermal API usage in the patches to work with the recent commit
ca1b9a9eb3fd ("thermal/drivers/qcom: Switch to new of API")
