xenvm: drivers: serial: Implement serial interface to Xen PV console This commit adds minimal support of Xen hypervisor console via UART-like driver. Implementation allows to use poll_in/poll_out char interface for uart_console.c driver directly to HV console instead of using Xen virtual PL011 UART. Future implementation will support interrupt driven interface on Xen event channels, currently it is under development. Also this commit introduces early console_io Xen interface, which allows to receive printk/stdout messages quickly after start, but requires Xen, built with CONFIG_DEBUG option.

xen: change HVM functions signature to run it for other domains This commit adds possibility to call hypervisor HVM parameter functions for specified domain (instead of only DOMID_SELF). It is needed for configuring domains, that were created from Zephyr control domain. Signed-off-by: Dmytro Firsov <dmytro_firsov@epam.com>
