The exynos dwmmc Ip has 2 stage divider. The first divider Register is in the vendor specific region of the dwmmc core (CLK_SEL), and second is part of the dwmmc generic registers (CLK_DIV). The goal of this patch is to maintain a 100MHz clock output before dividing it further by using the CLK_DIV. Depending on the card enumeration, it can be further divided by writing a correct divider in the dwmmc CLK_DIV register.
