msm: msm_bus: Add support for multiple ops in rules engine

Rules engine enables implementing SoC level workaround for system
performance issues allowing users to define these workaround rules.
Currently the rules only allow homogenous comparison operations against
a singular threshold. Expanding this to allow heterogenous comparison
operations against multiple thresholds thus allowing definition of more
complicated rules.
