arm64: dts: rockchip: Add HYM8563 RTC for Khadas Edge 2L

Browse Source 
The Khadas Edge 2L uses an on-board HYM8563 RTC connected to
I2C2. Enable it and expose its 32.768kHz clock output so later
board-level patches can reference it as the LPO clock source for
the AP6275P wireless module.

Mark the RTC as a wakeup source as well.
