[PATCH 2/2] board: rock5b-rk3588: add memory gaps into kernel's DTB

RK3588 has two memory gaps when using 16 GiB DRAM size: [0x3fc00 , 0x3fc50] and [0x3fff0 , 0x3] If the kernel is agnostic to these gaps, accessing the area causes a SError panic. Hence, add reserved memory areas in kernel's DTB before booting. Signed-off-by: Eugen Hristev --
