serial: fsl_lpuart: remove RTSCTS handling from get_mctrl()
[ Upstream commit
e60c2991f18bf221fa9908ff10cb24eaedaa9bae ]
The wrong code in set_mctrl() was already removed in commit
2b30efe2e88a
("tty: serial: lpuart: Remove unnecessary code from set_mctrl"), but the
code in get_mctrl() wasn't removed. It will not return the state of the
RTS or CTS line but whether automatic flow control is enabled, which is
wrong for the get_mctrl(). Thus remove it.
