[PATCH v4 2/2] counter: ti-eqep: Use devm_counter_add()

[phucduc.bui@gmail.com]

From: bui duc phuc <phucduc.bui@gmail.com>

Use devm_counter_add() instead of counter_add() to automatically
unregister the counter when the device is removed or probe fails.

This makes ti_eqep_remove() unnecessary, so remove it.
