## Summary
Add EHCI and OHCI USB host drivers for the Ingenic JZ4780 SoC, derived from
the existing sama5 implementation.
Additionally, introduce the display controller driver using code ported from
FreeBSD under its original license terms. Note that this driver lacks EDID
support and is currently hardcoded to 1360x768.
Update the linker script memory layout to utilize the full 256 MiB RAM,
excluding the 8 MiB reserved at the top of memory for the framebuffer.
## Testing
Used MIPS CI20 board.
Connected mouse directly to the CI20 port to force OHCI use.
Used tc command to verify that mouse works.
nsh> tc

Repeated the same test with mouse connected through a hub to test EHCI
controller.
