Implement support for CONFIG_SERIAL_MULTI into MCF serial driver.
This driver was so far only usable directly, but this patch also adds
support for the multi method. This allows using more than one serial
driver alongside the MCF driver. Also, add a weak implementation
of default_serial_console() returning this driver.

Applied the patch for baudrate divider value truncation for
serial_init to serial_setbrg as well.

The formula "counter = (u32) (gd->bus_clk / gd->baudrate) / 32"
can generate the wrong divisor due to integer division truncation.
Round the calculated divisor value by adding 1/2 the baudrate
before dividing by the baudrate.
