Remove symbols SERIAL_SAMSUNG_UARTS_4 and SERIAL_SAMSUNG_UARTS which
select the number of UART ports available on the SoC. Use the maximum
number of UART ports possible across the serial driver in place of
SERIAL_SAMSUNG_UARTS. Removal of these symbols also helps in Exynos7
serial enablement.

Build tested using s3c2410_defconfig, s3c6400_defconfig, exynos_defconfig
and arm64's defconfig with and without the serial driver enabled. Boot tested
on Exynos5420 and Exynos7.
