Subject: [PATCH v2] x86/defconfig: Enable CONFIG_USB_XHCI_HCD

A spanking new machine I just got has all but one USB ports wired as 3.0.
Booting defconfig resulted in no keyboard or mouse, which was pretty
uncool.  Let's enable that -- USB3 is ubiquitous rather than an oddity.
As 'y' not 'm' -- recovering from initrd problems needs a keyboard.

v2: also i386

While real 32-bit machines are ancient, folks tend to test such kernels on
something modern, thus you have a good point.  Changed.
