Current patch series introduces device tree mapping for RISC-V
and necessary things for that such as:
- Fixmap mapping
- pmap
- Xen page table processing
Also, it introduces common stuff for working with fdt which is
based on the patches from [1]:
[PATCH v4 2/6] xen/device-tree: Move Arm's setup.c bootinfo functions to common
[PATCH v4 3/6] xen/common: Move Arm's bootfdt.c
All changes which were done on top of Shawn's patches please find in "Changes" section
of each patch.
Also there is another one depenency:
RISCV basic exception handling implementation [2]

Changes in v2:
- Update the cover letter message
- introduce fixmap mapping
- introduce pmap
- introduce CONFIG_GENREIC_PT
- update use early_fdt_map() after MMU is enabled.
