xen: pvblock: Add initial support for para-virtualized block driver Add initial infrastructure for Xen para-virtualized block device. This includes compile-time configuration and the skeleton for the future driver implementation. Add new class UCLASS_PVBLOCK which is going to be a parent for virtual block devices. Add new interface type IF_TYPE_PVBLOCK. Implement basic driver setup by reading XenStore configuration.

config PVBLOCK
bool "Xen para-virtualized block device"
xen: Fix Kconfig dependencies XEN config can be enabled by other platforms (even it doesn't need to make sense) that's why fix dependencies. XEN (xenbus.c) requires sscanf (also pvblock needs it). And PVBLOCK is inside drivers/xen folder which requires XEN to be enabled. Signed-off-by: Michal Simek <michal.simek@amd.com> Reviewed-by: Heinrich Schuchardt <heinrich.schuchardt@canonical.com>

This driver implements the front-end of the Xen virtual
block device driver. It communicates with a back-end driver
in another domain which drives the actual block device.
