[PATCH] ARM: dts: exynos: Fix invalid maximum voltage for buck9 supplying SD card

[Krzysztof Kozlowski]

The buck9 regulator of S2MPS11 PMIC had incorrect maximum voltage -
lower by 5 mV than specified by datasheet. This buck9 provides power to
other regulators, including LDO13 and LDO19 which supply the MMC2 (SD
card).

When constraints were applied, the depending regulators were not
providing enough power, leading to SD card detection errors:
	mmc1: card never left busy state
	mmc1: error -110 whilst initialising SD card
