Eddie James c3de96686d mmc: sdhci-of-aspeed: Fix clock divider calculation
commit ebd4050c61 upstream.

When calculating the clock divider, start dividing at 2 instead of 1.
The divider is divided by two at the end of the calculation, so starting
at 1 may result in a divider of 0, which shouldn't happen.
