'div_reg' is a pointer. Assign NULL instead of 0.

The function socfpga_clk_init() can support clocks that do not have a divider
register, but a fixed-divider that can be read from DTS. Therefore, the "reg"
property is not a failing condition for socfpga_clk_init().

The SD/MMC clock is named "sdmmc_clk", and NOT "mmc_clk". Because of this,
the SD driver was getting the incorrect clock value. This prevented the
SD driver from initializing correctly.

Add support to gate the clocks that directly feed peripherals. For clocks
with multiple parents, add the ability to determine the correct parent,
and also set parents. Also add support to calculate and set the clocks'
rate.
