arm64: dts: fsd: fix drive strength macros as per FSD HW UM

Browse Source 
Drive strength macros defined for FSD platform is not reflecting actual
names and values as per HW UM. FSD SoC pinctrl has following four levels
of drive-strength and their corresponding values:
Level-1 <-> 0
Level-2 <-> 1
Level-4 <-> 2
Level-6 <-> 3

The commit 684dac402f ("arm64: dts: fsd: Add initial pinctrl support")
used drive strength macros defined for Exynos4 SoC family. For some IPs
the macros values of Exynos4 matched and worked well, but Exynos4 SoC
family drive-strength (names and values) is not exactly matching with
FSD SoC.

Fix the drive strength macros to reflect actual names and values given
in FSD HW UM.
