tty: serial: samsung: Declare earlycon for Exynos850

Browse Source 
It makes it possible to use just "earlycon" param in kernel cmdline
on Exynos850 based boards instead of "earlycon=exynos4210,0x13820000",
as described in [1]:

    When used with no options, the early console is determined by
    stdout-path property in device tree's chosen node
