Add an additional reserved memory region for the BL32 trusted firmware
shipping in Beelink g12b devices. This fixes a long running issue with
boxes booting from Vendor u-boot where the board wedges during boot or
soon after due to the (un)reserved region being overwritten.
Fixes commit 93db2ce05204 ("arm64: dts: meson: add initial Beelink GS-King-X device-tree")
