feat(rockchip): increase FDT Buffer for Rockchip Devices

Modify the FDT buffer for Rockchip devices to 384KiB. This is done to
allow us to pass mainline devicetrees with symbols through Arm Trusted
Firmware. 384KiB was chosen as 512KiB is very near the maximum
supported with the current reserved memory. As of kernel version 6.13,
the largest devicetree with symbols enabled is 215KiB, and the largest
Rockchip devicetree with symbols enabled is 176KiB
(rk3588-evb1-v10.dtb).
