[ARM] omap: don't use clkops_omap2_dflt_wait for non-ICLK/FCLK clocks

[ARM] omap: don't use clkops_omap2_dflt_wait for non-ICLK/FCLK clocks

The original code in omap2_clk_wait_ready() used to check the low 8
bits to determine whether they were within the FCLKEN or ICLKEN
registers.  Specifically, the test is satisfied when these offsets
are used:

 CM_FCLKEN, CM_FCLKEN1, CM_CLKEN, OMAP24XX_CM_FCLKEN2, CM_ICLKEN,
 CM_ICLKEN1, CM_ICLKEN2, CM_ICLKEN3, OMAP24XX_CM_ICLKEN4
 OMAP3430_CM_CLKEN_PLL, OMAP3430ES2_CM_CLKEN2

If one of these offsets isn't used, omap2_clk_wait_ready() merely
returns without doing anything.  So we should use the non-wait clkops
version instead and eliminate that conditional.
