MMC core now supports binding to a specific ID, which is very handy for
embedded devices, like Nexus 7, because MMC ID may change depending on
kernel version or configuration which affects MMC driver probe order.

This property was supposed to be upstreamed, but it was NAKed recently
in a favor to a better approach of firmware loading. It also turned
out that the firmware loading isn't really necessary because it's stored
in a non-volatile memory inside of the touchscreen controller and
previously the FW loading was needed in order to get touchscreen working,
but it actually was a TS driver problem which is resolved now. Hence
remove the unsupported property.

Applied to for-5.10/arm/dt, though I did move the new aliases so that
they are alphabetically sorted.

Applied to for-5.9/arm/dt, but sorted these alphabetically as well.
