USB: gadget: Introduce ci13xxx_udc_driver struct

Introduces ci13xxx_udc_driver struct for bus glue drivers to hint
ci13xxx_udc core about their special requirements.  The flags include
avoiding hardware register access when controller is not in peripheral
mode, enabling pull-up upon VBUS, disabling streaming mode and dependency
on transceiver driver.

Initialize gadget_ops in udc_probe so that transceiver can notify VBUS
presence even when no gadget driver is bounded.

A notify_event callback is embedded in the same struct. This patch implements
two events called CONTROLLER_RESET_EVENT and CONTROLLER_STOPPED_EVENT to
notify the bus glue driver after resetting and stopping the controller for
performing SoC specific quirks.

USB: gadget: file_storage: put_device() in error recovery

This commit fixes some issues with File-backed Storage Gadget
error recovery when registering LUN's devices.

First of all, when device_register() fails the device still
needs to be put.  However, because lun_release() decreases
fsg->ref reference counter the counter must be incremented
beforehand.

Second of all, after any of the device_create_file()s fails,
device_unregister() is called which in turn (indirectly) calls
lun_release() which decrements fsg->ref.  So, again, the
reference counter must be incremented beforehand.

Lastly, if the first or the second device_create_file()
succeeds, the files are never removed.  To fix it,
device_remove_file() needs to be called.  This is done by
simply marking LUN as registered prior to creating files so
that fsg_unbind() can handle removing files.

initramfs: Fix initramfs size for 32-bit arches

Commit ffe8018c3424 ("initramfs: fix initramfs size calculation") broke
32-bit big-endian arches like (on ARAnyM):

    VFS: Cannot open root device "hda1" or unknown-block(3,1)
    Please append a correct "root=" boot option; here are the available partitions:
    fe80         1059408 nfhd8  (driver?)
      fe81          921600 nfhd8p1 00000000-0000-0000-0000-000000000nfhd8p1
      fe82          137807 nfhd8p2 00000000-0000-0000-0000-000000000nfhd8p2
    0200            3280 fd0  (driver?)
    0201            3280 fd1  (driver?)
    0300         1059408 hda  driver: ide-gd
      0301          921600 hda1 00000000-0000-0000-0000-000000000hda1
      0302          137807 hda2 00000000-0000-0000-0000-000000000hda2
    Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(3,1)

As pointed out by Kerstin Jonsson <kerstin.jonsson@ericsson.com>, this
is due to CONFIG_32BIT not being defined, so the initramfs size field is
done as a 64-bit quad.  On little-endian (like x86) this doesn matter,
but on a big-endian machine the 32-bit reads will see the (zero) high
bits.

Only mips, s390, and score set CONFIG_32BIT for 32-bit builds, so fix it for
all other 32-bit arches by inverting the logic and testing for CONFIG_64BIT,
which should be defined on all 64-bit arches.

nfsd4: initialize delegation pointer to lease

The NFSv4 server was initializing the dp->dl_flock pointer by the
somewhat ridiculous method of a locks_copy_lock callback.

Now that setlease uses the passed-in lock instead of doing a copy,
dl_flock no longer gets set, resulting in the lock leaking on delegation
release, and later possible hangs (among other problems).

So, initialize dl_flock and get rid of the callback.
