ARM: dts: rockchip: fix vref-supply for &saradc node rk3288 firefly reload

A test with the command below gives this error:

arch/arm/boot/dts/rk3288-firefly-reload.dt.yaml: saradc@ff100000:
'vref-supply' is a required property

PMIC Channel OUT11 with powername 'vcc_18'
(connected through R155 bridge with 'vccio_wl')
is used for the recovery key and ADC_AVDD_1V8.

Fix error by adding 'vcc_18' as vref for the saradc.
