This adds two small inlines to the gadget stack, which will
often evaluate to compile-time constants. That can help
shrink object code and remove #ifdeffery.
- gadget_is_dualspeed(), currently always a compile-time
constant (depending on which controller is selected).
- gadget_is_otg(),
Following this are several minor gadget stack updates:
- Add gadget_is_dualspeed() and gadget_is_otg() predicates,
which can help remove #ifdeffery and associated cleanups.
Includes updates to fsl_usb2_udc, omap_udc, and gadgetfs.

The following short patch series includes the following:
Various cleanups suggested for the previous patches;
Rework the spinlock usage in the root-hub URB code;
Separate out endpoint queue management and transfer-buffer
DMA mapping into their own
This patch (as951) cleans up a few loose ends from earlier patches.
Redundant checks for non-NULL urb-dev are removed, as are checks of
urb-dev-bus (which can never be NULL). Conversely, a check for
non-NULL urb-ep is added to the unlink paths.
A homegrown round-down-to-power-of-2 loop is
This patch (as952) adjusts the spinlock usage in the root-hub
emulation part of usbcore, to make it match more closely the pattern
used by regular host controller drivers. To wit: The private lock
(usb_hcd_root_hub_lock) is held throughout the important parts, and it
is dropped temporarily
This patch (as953) separates out three key portions from
usb_hcd_submit_urb(), usb_hcd_unlink_urb(), and usb_hcd_giveback_urb()
and puts them in separate functions of their own. In the next patch,
these functions will be called directly by host controller drivers
