24xx clock fixes: DSP, 54MHz APLL

Hello,

these patches clean up the structure of the DSP clocks on the OMAP24xx platforms. They remove redundant clocks and rate structures, and fix the DSP driver code to use the correct clock name on 2430. DSP i-clock source selection is moved into a separate clock, dsp_irate_ick, to facilitate some of this consolidation.

Also, in omap2_clk_fixed_enable(), it turns out that we were looking for the wrong IDLEST bit to test if the 54MHz APLL was locked - fix this.

This series resolves the boot-time clock warnings that appear on 2430SDP:

clock: Could not find parent clock iva2_1_fck in clksel array of clock iva2_1_ick

omapdsp: could not acquire dsp_ick handle

Clock apll54_ck didn't enable in 100000 tries

Boot-tested on N800 and 2430SDP. Comments welcome.

- Paul
