mmc: dw_mmc: Remove mshc alias support

Remove the long-deprecated mshc alias support, as the mmc core already
provides alias functionality through the standard mmc alias. This eliminates
the redundant dual-alias system. The driver now obtains the controller ID
from struct mmc_host::index(supplied by mmc alias) instead of the legacy mshc
alias.
