[PATCH] arm64: dts: mediatek: mt8188-geralt: Enlarge SCP core0 memory region

[Justin Yeh]

The SCP firmware in linux-firmware for this platform
(mediatek/mt8188/scp_c0.img) supports MDP, which the mdp3-rdma node
drives through scp_c0. On top of the segments it loads, the firmware
allocates a 1 MiB DMA region at 0x50800000 at run time. That lies
outside the 8 MiB reserved for SCP core0, so Linux is free to allocate
over memory the firmware uses.

Enlarge the region to 9 MiB. apu_mem starts at 0x55000000, so no other
reserved region has to move.
