[Armbian build PR] - rk3318: add uboot Recovery button support

[RSS Bot]

Description

Add uboot 'button' cmd and add Recovery button to rk3318 uboot dts.

In the linux kernel dts button is labeled lowercase "recovery", but I've chosen "Recovery" as it is more frequent in uboot dts'es:

$ (cd cache/sources/u-boot-worktree/u-boot/v2022.07/arch/arm/dts; grep -ir 'label.*"recovery"' .)
./rk3399-nanopc-t4.dts:                 label = "Recovery";
./rk3399-khadas-edge.dtsi:                      label = "Recovery";
./rk3399-roc-pc.dtsi:                   label = "Recovery";
./rk3328-rock-pi-e.dts:                 label = "Recovery";
./rk3066a-mk808.dts:                    label = "recovery";
./rk3399-nanopi-m4b.dts:                        label = "Recovery";

How Has This Been Tested?

• [x] boot rk3318 with modified uboot.cmd to test new command:

if button Recovery; then
    echo "Recovery ON"
else
    echo "Recovery OFF"
fi
