ARM: dts: exynos: Fix pinctrl definition for eMMC RTSN line on Odroid X2/U3
Commit 225da7e65a03 ("ARM: dts: add eMMC reset line for
exynos4412-odroid-common") added MMC power sequence for eMMC card of
Odroid X2/U3. It reused generic sd1_cd pin control configuration node
and only disabled pull-up. However that time the pinctrl configuration
was not applied during MMC power sequence driver initialization. This
has been changed later by commit d97a1e5d7cd2 ("mmc: pwrseq: convert to
proper platform device").
It turned out then, that the provided pinctrl configuration is not
correct, because the eMMC_RTSN line is being re-configured as 'special
function/card detect function for mmc1 controller' not the simple
'output', thus the power sequence driver doesn't really set the pin
value. This in effect broke the reboot of Odroid X2/U3 boards. Fix this
by providing separate node with eMMC_RTSN pin configuration.
