clk: ti: am33xx: keep WKUP_DEBUGSS_CLKCTRL enabled
[ Upstream commit 1e0d75258bd09323cb452655549e03975992b29e ]
As described in AM335x Errata Advisory 1.0.42, WKUP_DEBUGSS_CLKCTRL
can't be disabled - the clock module will just be stuck in transitioning
state forever, resulting in the following warning message after the wait
loop times out:
l3-aon-clkctrl:0000:0: failed to disable
Just add the clock to enable_init_clks, so no attempt is made to disable
it.
