Subject: [PATCH v2 1/2] arm64: dts: exynos: drop mshc aliases

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.

Signed-off-by: Henrik Grimler <henrik@...mler.se>

Changes since v1:
* Add mmc-ddr-1_8v property so that capabilities stays the same
  when mshc0 alias is removed
