clk: ti: Initialize clocks for dm816x The clocks on ti81xx are not compatible with omap3. On dm816x the clock source is a FAPLL (Flying Adder PLL), and on dm814x there seems to be an APLL (All Digital PLL). Let's fix up things for dm816x in preparation for adding the FAPLL support. As we already have a dummy ti81xx_dt_clk_init() in place, let's use that for now to avoid adding a dependency to the omap patches. Later on if somebody adds dm814x support we can split the ti81xx_dt_clk_init() clock init function as needed.

ARM: OMAP2+: Add support for initializing dm814x clocks Let's add a minimal clocks for dm814x to get it booted. This is mostly a placeholder and relies on the PLLs being on from the bootloader. Note that the divider clocks work the same way as on dm816x and am335x.
