Raul E Rangel de23f0b757 mmc: sdhci: sdhci-pci-o2micro: Check if controller supports 8-bit width ...

The O2 controller supports 8-bit EMMC access.

JESD84-B51 section A.6.3.a defines the bus testing procedure that
`mmc_select_bus_width()` implements. This is used to determine the actual
bus width of the eMMC.
