i.MX: serial: Add baud rate calculation convenience functions
Add two functions to calculate values for UBMR and UBIR registers. This way both early serial initalization code and serial_imx.c can use them and not duplicate the code. Singed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
