[PATCH][next] counter: microchip-tcb-capture: remove ATMEL_TC_ETRGEDG_NONE bit check

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

The macro ATMEL_TC_ETRGEDG_NONE is defined as 0 << 8 which is zero and
hence the check cmr & ATMEL_TC_ETRGEDG_NONE can never be true. Since
*action is already assigned MCHP_TC_SYNAPSE_ACTION_NONE then this check
and set is redundant dead code and can be removed.

Addresses-Coverity: ("Logically dead code")
