xen: Create a new file xen_pvdev.c
The purpose of the new file is to store generic functions shared by frontend and backends such as xenstore operations, xendevs. Signed-off-by: Quan Xu <quan.xu@intel.com> Signed-off-by: Emil Condrea <emilcondrea@gmail.com> Signed-off-by: Stefano Stabellini <sstabellini@kernel.org> Signed-off-by: Quan Xu <xuquan8@huawei.com> Acked-by: Anthony PERARD <anthony.perard@citrix.com>
