The Rockchip-specific SDHCI wrapper does not process the 'bus-width' property in the SDHCI node. Consequently, the bus is always kept in 4bit mode, even if 8bit wide operation is available, supported and requested in the DTS.
This change adds processing of the 'bus-width' property and sets the host capability flag for an 8bit wide bus, if set to 8. As the logic in sdhci.c does not support clearing the 4bit capability, we assume that 4bit operation is always supported.
