arm64: dts: rockchip: rk3308b-evb-v10 modify vccio_flash to 3.3v

Browse Source 
The power supply for vccio_flash is depends on GPIO0_A4(pin R3 on SoCs),
if GPIO0_A4 input high, vccio_flash = 1.8v
if GPIO0_A4 input low,  vccio_flash = 3.3v

Reference to rk_board_init() in arch/arm/mach-rockchip/rk3308/rk3308.c,
it has configure vccio3 io-domain, so here needn't to do more.

BUT lack of vccio3 will make regulator summary hard to read, it's better
to configure vccio3 = <&vccio_flash> after double check its voltage.
