Subject: [PATCH] serial: mxs-auart: fix baud rate range

commit df57cf6a879502cd6e5559c1f2d6db12128e074f upstream.

Currently mxs-auart doesn't care correctly about the baud rate divisor.
According to reference manual the baud rate divisor must be between
0x000000EC and 0x003FFFC0. So calculate the possible baud rate range
and use it for uart_get_baud_rate().
