  To: linux-arm-kernel; +Cc: Shawn Guo, Alexander Shiyan, kernel

This patch adds bus-width property for esdhc1 to avoid mmc
core warning: "bus-width" property is missing, assuming 1 bit.
Additionally, the patch removes this property for boards where
4-bit width is already specified, and adds 1-bit width for
boards where this property is omitted.
