Subject: [PATCH] pch_uart: Fix rx error interrupt setting issue

commit 9539dfb7ac1c84522fe1f79bb7dac2990f3de44a upstream.

Rx Error interrupt(E.G. parity error) is not enabled.
So, when parity error occurs, error interrupt is not occurred.
As a result, the received data is not dropped.

This patch adds enable/disable rx error interrupt code.
