similar to: [PATCH v4] vhost: disable for OABI

vhost is currently broken on the default ARM config. The reason is that that uses apcs-gnu which is the ancient OABI that is been deprecated for a long time. Given that virtio support on such ancient systems is not needed in the first place, let's just add something along the lines of depends on !ARM || AEABI to the virtio Kconfig declaration, and add a comment that it has to do with

From: Erwan Yvin <erwan.yvin at stericsson.com> Add the CAIF Virtio shared memory driver for talking to a modem. This CAIF Link layer communicates to the modem over shared memory. It is implemented as a virtio_driver. The underlying virtio device is managed by the remoteproc framework. The Virtio queue is used for transmitting data to the modem, and the new vringh is used for receiving
