[PATCH] hw/hyperv: Include missing headers

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

Include missing headers in order to avoid when refactoring
unrelated headers:

BTW who maintains this code?

$ ./scripts/get_maintainer.pl -f hw/hyperv/hyperv.c
get_maintainer.pl: No maintainers found, printing recent contributors.
get_maintainer.pl: Do not blindly cc: them on patches!  Use common sense.
