ARM: dts: exynos: replace mshc0 alias with mmc-ddr-1_8v property

Previously, the mshc0 alias has been necessary so that
MMC_CAP_1_8V_DDR | MMC_CAP_8_BIT_DATA are set for mshc_0/mmc_0.
However, these capabilities should be described in the device tree so
that we do not have to rely on the alias.

The property mmc-ddr-1_8v replaces MMC_CAP_1_8V_DDR, while bus_width =
<8>, which is already set for all the mshc0/mmc0 nodes, replaces
MMC_CAP_8_BIT_DATA.

Also drop other mshc aliases as they are not needed.
