The current implementation uses both, host and card capabilites to derive
the maximum bus width to be used. However, in cases where a MMC device is
not connected to the host via shdc using the full bus width of 8 lines,
device initialization fails. Introducing the `bus-width` property
circumvents this by reducing the host bus capabilites and forcing
communication with the MMC device using 1, 4 or 8 lines.
