Add Qualcomm Technologies, Inc. PMIC PON log device bindings. The
PMIC PON log device parses power-on, power-off, and fault messages
stored in a binary log within the SDAM memory found on some QTI
PMIC devices.
This is a snapshot of the file qcom,pmic-pon-log.txt taken
as of qcom-6.1 branch
commit 8e58283f0a59 ("dt-bindings: soc: qcom: pmic-pon-log:
define bindings for multiple nvmem") which was then converted
to yaml format.
