vbox: add HAS_IOPORT dependency
The vboxguest driver depends on port I/O for debug output:
include/asm-generic/io.h:626:15: error: call to '_outl' declared with attribute error: outl() requires CONFIG_HAS_IOPORT
626 | #define _outl _outl
include/asm-generic/io.h:663:14: note: in expansion of macro '_outl'
663 | #define outl _outl
| ^~~~~
drivers/virt/vboxguest/vboxguest_utils.c:102:9: note: in expansion of macro 'outl'
102 | outl(phys_req, gdev->io_port + VMMDEV_PORT_OFF_REQUEST);
| ^~~~
Most arm64 platforms don't actually support port I/O, though it is
currently enabled unconditionally. Refine the vbox dependency to allow
turning HAS_IOPORT off in the future when building for platforms without
port I/O and allow compile-testing on all architectures.
