User input data is passed in from userspace through debugfs interface
of supply lm core to validate supply lm core functionality. Ensure
user buffer size is not greater than expected stack buffer size
to avoid out of bounds array accesses.

Remove supply lm devices init and de-init from probe function.
Devices initialization happens only when user requests to enable it.
Cleanup driver code in the error path to avoid any unexpected
behaviour.

Cancel sensor trip for both high and low thresholds and fix memory
leak in sensor_mgr_remove_threshold API. Modify sensor manager APIs
to use client device to allocate/release memory for thresholds
using devm_kzalloc and devm_kfree.

This driver is a current limit management module to help manage
instantaneous peak current drawn by multiple subsystems on shared
supply. The inputs to the mitigation algorithm are current states
of different subsystems sharing this supply like cpu frequency,
gpu frequency, number of cores online, soc temperature, core leakage,
and modem state. It throttles cpu frequency and limits number of
online cores to reduce the dynamic current so as to keep the total
current drawn from supply in safe limits.
