[PATCH 4/4] xen/char: pv_console: Fix MISRA C 2012 Rule 8.4 violation

[Xenia Ragiadakou <burzalodowa@xxxxxxxxx>]

The function pv_console_evtchn() is defined in the header <xen/pv_console.h>.
If the header happens to be included by multiple files, this can result in
linker errors due to multiple definitions,
So, it is more appropriate to resolve this MISRA C 2012 Rule 8.4 violation
warning by making pv_console_evtchn() inline with internal linkage.
