[PATCH 1/1] clk: ti: am33xx: keep WKUP_DEBUGSS_CLKCTRL enabled

[Alexander Stein]

From: Matthias Schiffer <matthias.schiffer@xxxxxxxxxxxx>

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.
