Using an array to report monitor stats instead of hard coded variable
names would allow for cleaner implementations of some cache hwmon
device drivers.

The cache monitoring devices might have more than one IRQ to handle
or might have notifications from other drivers instead of using actual
IRQs. So, refactor the governor to move the IRQ handling to the cache
monitoring device specific drivers and just provide an API that can be
used to request a re-evaluation.
The device specific driver can call this API to request an immediate
re-evaluation whenever the cache request has exceeded the previously
set limit instead of waiting for the periodic update.

The refactor allows the governor to support multiple devfreq devices.
This is done by having different HW monitor instances register their
capability to monitor different devfreq devices and then picking the
right HW monitor based on which devfreq device is using this governor.
