OMAP: clockdomain: Arch specific funcs to handle deps

Define the following architecture specific funtions for omap2/3
.clkdm_add_wkdep
.clkdm_del_wkdep
.clkdm_read_wkdep
.clkdm_clear_all_wkdeps
.clkdm_add_sleepdep
.clkdm_del_sleepdep
.clkdm_read_sleepdep
.clkdm_clear_all_sleepdeps

Convert the platform-independent framework to call these functions.
With this also move the clkdm lookups for all wkdep_srcs and
sleepdep_srcs at clkdm_init.

[paul@pwsan.com: fixed loop termination conditions in omap*_clkdm_clear_all_*();
 thanks to Kevin Hilman for finding and helping fix those bugs; also
 avoid re-resolving clockdomains during init; abstracted out clkdm_dep walk]
