HHI_SPICC_CLK_CNTL bits 25:23 controls spicc clk_sel.
It is missing fclk_div 2 and gp0_pll which causes the spicc module to output the incorrect clocks for spicc sclk at 2.5x the expected rate.
Add the missing clocks resolves this.

Sorry, this is an older version of the patch without Fixes tag from a mv error. I'm sending a v2, ignore this one.
