[ Upstream commit 574d6c59daefb51729b0640465f007f6c9600358 ]
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 684dac402f21 ("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.
