[PATCH] tools/libxc: use uint32_t for pirq in xc_domain_irq_permission

[Igor Druzhinin <igor.druzhinin@xxxxxxxxxx>]

Current unit8_t for pirq argument in this interface is too restrictive
causing failures on modern hardware with lots of GSIs. That extends down to
XEN_DOMCTL_irq_permission ABI structure where it needs to be fixed up
as well. Internal Xen structures appear to be fine. Existing users of
the interface in tree (libxl, ocaml and python bindings) are already using
int for pirq representation that should be wide enough.

Domctl interface version is needed to be bumped with this change but that
was already done by 918b8842a8 ("arm64: Change type of hsr, cpsr, spsr_el1
to uint64_t") in this release cycle.
