build/patch/kernel/archive/rockchip64-5.19/add-board-nanopi-r4s.patch

This patch is an adapted version of:
https://github.com/friendlyarm/kernel-rockchip/commit/0e2cbeb4b1e645f5827b54bf50c65577be3eb7b4

Adjusted:
 - do not mess with common Nano{Pi,PC}4 device tree (rk3399-nanopi4.dtsi)
 - disabled non existent bluetooth node at uart0
 - disabled usb_host1
