Alexandru Stefan ISAILA ea22bcd030 x86/altp2m: Add hypercall to set a range of sve bits ...

By default the sve bits are not set.
This patch adds a new hypercall, xc_altp2m_set_supress_ve_multi(),
to set a range of sve bits.
The core function, p2m_set_suppress_ve_multi(), does not break in case
of a error and it is doing a best effort for setting the bits in the
given range. A check for continuation is made in order to have
preemption on large ranges.
The gfn of the first error is stored in
xen_hvm_altp2m_suppress_ve_multi.first_error_gfn and the error code is
stored in xen_hvm_altp2m_suppress_ve_multi.first_error.
If no error occurred the values will be 0.
