ARM: SAMSUNG: serial: Add FRACVAL support for newer UART
Add support for the FRACVAL register on the newer UART blocks which provides
the same function as UDIVSLOT register but the FRACVAL is easier to implement.
To support UDIVSLOT register, UDIVSLOT table search is necessary though
supporting FRACVAL only needs the index value of UDIVSLOT table.
