xenvm: switch to Xen PV console instead of PL011 SBSA

Browse source 
This commit removes usage of Xen emulated PL011 SBSA UART in favor of
Xen PV console minimal implementation. Now boot log and application
output can be directly taken from hypervisor domain console, instead of
virtual UART.

Also Xen VM doc was updated according to these changes.
