Subject: [PATCH 1/2] usb: host: remove USB_ARCH_HAS_?HCI

USB_ARCH_HAS_EHCI, USB_ARCH_HAS_OHCI, and USB_ARCH_HAS_XHCI were made
obsolete in v3.11. They have not been used ever since. Setting them has
no effect. They can safely be removed.

Signed-off-by: Paul Bolle <pebolle@...cali.nl>

Tested with "git grep".

Note that the comment in this Kconfig file (that is also removed)
suggests to first remove the select statements for these symbols and
then the symbols themselves. But I think it makes more sense to first
delete these three symbols and then remove the selects statements (as
that is removing a second order effect). But it could just as well be
done with just one patch, I'd say.
