arm64: dts: amlogic: t7: khadas-vim4: fix memory layout for 8GB RAM
The Khadas VIM4 features 8GB of LPDDR4X RAM. The previous memory node
mapped a single incorrect region. This caused the kernel to map MMIO
and secure firmware (ATF/TrustZone) memory holes as standard RAM,
leading to an Asynchronous SError Interrupt during early boot
(paging_init) when the kernel attempted to clear those pages.
Fix this by splitting the 8GB memory layout into three separate
regions to properly avoid the memory holes (e.g., 0xe0000000 -
0xffffffff):
- 3.5GB @ 0x000000000
- 3.5GB @ 0x100000000
- 1.0GB @ 0x200000000
