[U-Boot] [PATCH 2/4] rv1108: Enable eMMC support

[Otavio Salvador]

In order to be able to build the Rockchip eMMC driver
on rv1108, the CONFIG_BOUNCE_BUFFER option needs to be
selected.

Select it like it is done on the other Rockchip SoC common files.

This also adds the pinctrl handles to enable the use of eMMC on custom
boards (as minievk) and makes it easier for later addition.
