[PATCH 2/3] clk: mvebu: adjust clock handling for the CP110 system controller

This commit adds support for the GOP_DP gatable clock found in the
CP110 system controller. This clock is controlled by bit 9, and has
clock 18 as its parent. Therefore, clock 18 is in fact not only
controlling SD/MMC, but also GOP, but it is renamed as SD_MMC_GOP
accordingly.
