Computed from the build architecture defines, EM_HOST and EF_HOST give
values that can be used in dwarf register lookup. Place in
dwarf-regs.h so the value can be shared. Move some dwarf-regs.c
constants used for EM_HOST to dwarf-regs.h. Add CSky constants that
may be missing.
In disasm.c add an include of dwarf-regs.h as the included
arch/*/annotate/instructions.c files make use of the constants and we
want the elf.h/dwarf-regs.h dependency to be explicit.
