Subject: [PATCH 1/2] thermal/drivers/qcom/lmh: Use driver data as flags instead of bool

Currently the OF driver data is used to determine whether to manually
enable the LMH algorithms through secure calls. In preparation for
introducing support for SoCs with a configuration that differs from
both SDM845 and SM8150, convert this to a set of bitflags for more
flexibility.
