e978e9b977 c67x00-hcd: constify hc_driver structures
The hc_driver structure is only passed as the first argument to
usb_create_hcd, which is declared as const.  Thus the hc_driver structure
itself can be const.

Done with the help of Coccinelle.

3c9740a117 usb: hcd: move controller wakeup setting initialization to individual driver
Individual controller driver has different requirement for wakeup
setting, so move it from core to itself. In order to align with
current etting the default wakeup setting is enabled (except for
chipidea host).

Pass compile test with below commands:
	make O=outout/all allmodconfig
	make -j$CPU_NUM O=outout/all drivers/usb

968b822c00 USB: Remove the SAW_IRQ hcd flag
The HCD_FLAG_SAW_IRQ flag was introduced in order to catch IRQ routing
errors: If an URB was unlinked and the host controller hadn't gotten
any IRQs, it seemed likely that the IRQs were directed to the wrong
vector.

This warning hasn't come up in many years, as far as I know; interrupt
routing now seems to be well under control.  Therefore there's no
reason to keep the flag around any more.  This patch (as1495) finally
removes it.

541c7d432f USB: convert usb_hcd bitfields into atomic flags
This patch (as1393) converts several of the single-bit fields in
struct usb_hcd to atomic flags.  This is for safety's sake; not all
CPUs can update bitfield values atomically, and these flags are used
in multiple contexts.

The flag fields that are set only during registration or removal can
remain as they are, since non-atomic accesses at those times will not
cause any problems.

(Strictly speaking, the authorized_default flag should become atomic
as well.  I didn't bother with it because it gets changed only via
sysfs.  It can be done later, if anyone wants.)
