counter: microchip-tcb-capture: Fix CMR value check
to my staging git tree which can be found at

The patch will show up in the next release of the linux-next tree

Subject: counter: microchip-tcb-capture: Fix CMR value check
The ATMEL_TC_ETRGEDG_* defines are not masks but rather possible values
for CMR. This patch fixes the action_get() callback to properly check
for these values rather than mask them.
Fixes: 106b104137fd ("counter: Add microchip TCB capture counter")
