ARM: dts: meson8b: odroidc1: enable the SDHC controller
Odroid-C1 has an eMMC connector where users can optionally install an
eMMC module. The eMMC modules run off a 1.8V VQMMC supply which means
that HS-200 mode can be used (this is the highest mode that the SDHC
controller supports). Enable the SDHC controller so eMMC modules can be
accessed.
