[Xen-devel] [PATCH for-next] tools/libxc: Drop broken xc_{get, set}_hvm_param() functions

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

xc_{get,set}_hvm_param() are deprecated because they truncate their value
parameter in 32bit builds of libxc, and are therefore unfit for use.

As there is only a single remaining user, switch that user over to
xc_hvm_param_get() and drop these functions completely.
