XHCI console works fine with UEFI boot, as Xen doesn't relocate itself. But on
legacy boot, relocation is a problem, as the hardware is programmed with
physical addresses of structures that are moved. Fix this by adding new console
init hooks. This series includes also few minor improvements that were useful
when working on the fix.

Marek Marczykowski-Górecki (5):
  console: add relocation hook
  drivers/char: Handle Xen relocation in the XHCI console driver
  drivers/char: make dbc_uart_dump() a bit more useful
  drivers/char: remove outdated comment in xhci driver
  console: support multiple serial console simultaneously
