Subject: [PATCH 8/8] counter: Remove unused member from struct counter_device

The functionality priv was designed for can better be accomplished using
container_of. All drivers have been converted, so drop this now unused
member.

Just one assignment was missed in the conversion of the ti-eqep driver.
This is unused and so can be safely dropped, too.
