clk: sunxi-ng: sun6i-rtc: clean up DT usage

Browse source

With sun6i-rtc compatible devices, the "ext-osc32k" clock input
is optional for the devices that support this input (r329 and onward).

Probably preparing for older SoC support, the driver does something funny
when parsing DT. It check if "ext-osc32k" is present in the clock-names and
if it is not, it uses the first clock as "ext-osc32k". This clock will
actually be the rtc bus clock so what the driver does is wrong.

At the moment, the driver does not support the older SoCs that would have
an external 32k clock provided on index #0 so just remove this quirk.
