OMAP2xxx: clock: fix interface clocks and clockdomains for modules in the WKUP domain
The parent of the interface clocks for GPTIMER1, MPU_WDT, SYNCTIMER_32K, SCM, WDT1, and the ICR (2430 only) were all listed as being l4_ck. This isn't accurate; these modules exist inside the WKUP domain, and the interface clock to these modules runs at the SYS_CLK rate rather than the CORE L4 rate. So, create a new clock "wu_l4_ick", similar to the OMAP3 "wkup_l4_ick", that serves as the parent for these clocks. Also, these clocks were listed as existing inside core_l4_clkdm; wkup_clkdm is probably more accurate. Signed-off-by: Paul Walmsley <paul@pwsan.com>
