[PATCH] arm64/defconfig: Restore built-in 9P rootfs support

[Anshuman Khandual <anshuman.khandual@arm.com>]

Commit d521c4ca039f ("arm64: defconfig: Switch Ethernet drivers to modules")
had changed 9P and virtio-9P support from built-in to modular instead. This
breaks simple kvmtool boots using a 9P root filesystem without an initramfs
, because the kernel must mount root filesystem before it can load the 9P
modules. Also there is no change in image size with these configs built-in.

Restore the relevant 9P options as built-in.
