feat(tc): factor in FVP/FPGA differences
Even though the FVP and FPGA are meant to be identical their RoS's (rest
of system) are different. Factor these in so the device tree works for
both. The differences are:
* addresses of GIC and UART
* displays (FPGA uses 4k)
* ethernet devices and SD card (it's non removable on the FPGA)
Their frequencies are also different. The FVP simulates certain
frequencies but isn't very sensitive when we disregard them. To keep
code similar, update them with the FPGA values. This keeps working on
FVP even if slightly incorrect.
Also add an option for the DPU to either use fixed clocks or SCMI set
clocks, hidden behind a flag. This is useful during bringup and because
SCMI may not necessarily work on FPGA.
