Add support for SiFive Premier P550 platform

Browse Source

The SiFive Premier P550 [1] is a new development board from SiFive
that is based on the ESWIN EIC7700X SoC.

The platform is interesting to the seL4 community as it implements
the RISC-V hypervisor extension meaning we now have real hardware to
evaluate RISC-V hypervisor changes to seL4. It also implements the
Sscofpmf extension and so we'll be able to get more experiment with
proper profiling on RISC-V.

Unfortunately, it seems we still do not have proper ASID suppor
according to [2].

The board comes in two configurations, 16GB and 32GB of memory.
This adds support for the 16GB model.

The DTS comes from SiFive's fork of Linux [3].
No modifications were made, any extra things are in the overlay.
