Implement memory_state_time, used by qcom,cpubw
New driver memory_state_time tracks time spent in different DDR
frequency and bandwidth states.
Memory drivers such as qcom,cpubw can post updated state to the driver
after registering a callback. Processed by a workqueue
Bandwidth buckets are read in from device tree in the relevant qualcomm
section, can be defined in any quantity and spacing.
The data is exposed at /sys/kernel/memory_state_time, able to be read by
the Android framework.
Functionality is behind a config option CONFIG_MEMORY_STATE_TIME
