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.
