OMAP3: clock data: Add "wkup_clkdm" in sr1_fck and sr2_fck

The smartreflex modules belong to an ALWON_FCLK clock domain that
does not have any SW control. The gating of that interface clock
is triggered by a transition of the WKUP clock domain to idle.

Attach both smartreflex instances on OMAP3 to the WKUP clock domain.

The missing clock domain field in srX_fck clock nodes was reported by
Kevin during the discussion about smartreflex on OMAP3:
