Hey folks,

This patchset adds serial driver support for Exynos8895 SoC. The main
difference from other exynos platforms is that fifosize is only
specified via the samsung,uart-fifosize DT property.

Newer Exynos platforms also specify fifosize via DT, so in such case
this compatible could be used with oneOf.

Changes in v2:
 - Grow the enum at gs101 instead of making a new if-else
 - Add r-b from Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>
