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.
