arm64: dts: rockchip: correct voltage selector on Firefly-RK3399

Without this patch the Firefly-RK3399 board boot process hangs after these
lines:

   fan53555-regulator 0-0040: FAN53555 Option[8] Rev[1] Detected!
   fan53555-reg: supplied by vcc_sys
   vcc1v8_s3: supplied by vcc_1v8

Blacklisting driver fan53555 allows booting.

The device tree uses a value of fcs,suspend-voltage-selector different to
any other board.

Changing this setting to the usual value is sufficient to enable booting
and also matches the value used in the vendor kernel.
