Relax condition of building the reset interface stubs in
drivers/usb/early/ehci-dbgp.c from USB_EHCI_HCD to just USB, to also
cover the chipidea driver re-using code from ehci-hcd.

Since there's no possible caller of dbgp_external_startup() and
dbgp_reset_prep() when !USB_EHCI_HCD, there's no point in building and
exporting these functions in that case. This eliminates a build error
under the conditions listed in the subject, introduced with the merge
f1c6872e4980bc4078cfaead05f892b3d78dea64.

Just like for the in-tree early console debug port driver, the
hypervisor - when using a debug port based console - also needs to be
told about controller resets, so it can suppress using and then
re-initialize the debug port accordingly.

Other than the in-tree driver, the hypervisor driver actually cares
about doing this only for the device where the debug is port actually
in use, i.e. it needs to be told the coordinates of the device being
reset (quite obviously, leveraging the addition done for that would
likely benefit the in-tree driver too).

Pull KGDB/KDB/usb-dbgp fixes and cleanups from Jason Wessel:
 "There are no new features, those will be delayed to the 3.7 window.
  There are only fixes/cleanup against the usual kernel churn and we are
  removing more lines than we add:

   - usb-dbgp - increase the controller wait time to come out of halt.
   - kdb - Remove unused KDB_FLAG_ONLY_DO_DUMP code and cpu in more prompt
   - debug core - pass NMI type on archs that provide NMI types"

* tag 'for_linux-3.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jwessel/kgdb:
  USB: echi-dbgp: increase the controller wait time to come out of halt.
  kernel/debug: Make use of KGDB_REASON_NMI
  kdb: Remove cpu from the more prompt
  kdb: Remove unused KDB_FLAG_ONLY_DO_DUMP

The default 10 microsecond delay for the controller to come out of
halt in dbgp_ehci_startup is too short, so increase it to 1 millisecond.

This is based on emperical testing on various USB debug ports on
modern machines such as a Lenovo X220i and an Ivybridge development
platform that needed to wait ~450-950 microseconds.

The two first HC capability registers (CAPLENGTH and HCIVERSION)
are defined as one 8-bit and one 16-bit register. Most HC
implementations have selected to treat these registers as part
of a 32-bit register, giving the same layout for both big and
small endian systems.

This patch adds a new quirk, big_endian_capbase, to support
controllers with big endian register interfaces that treat
HCIVERSION and CAPLENGTH as individual registers.

For all modules, change <module>-objs to <module>-y; remove
if-statements and replace with lists using the kbuild idiom; move
flags to the top of the file; and fix alignment while trying to
maintain the original scheme in each file.

None of the dependencies are modified.
