[PATCH v3 1/2] arm64: allwinner: a64: Add RTC clock to phandle 32kHz external oscillator

[Jagan Teki]

Outside of SOC few chips need external clock source
through RTC example Wifi chip. So RTC clock nodes to
phandle 32kHz external oscillator.

prefix rtc- with clock-output-names defined in
dt-binding to avoid confusion with existing osc32k name.
