Allow the firmware and enable GPIOs to sleep.

This fixes a `WARN_ON' and allows the driver to operate GPIOs which are
connected to I2C GPIO expanders.

When the device is disconnected from the driver, there is a "dangling"
reference count on the usb interface that was grabbed in the probe
callback.  Fix this up by properly dropping the reference after we are
done with it.

This was done entirely with mindless brute force, using

    git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
        xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'

to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.

Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.

For the same reason the 'flex' versions will be done as a separate
conversion.

This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:

Single allocations:	kmalloc(sizeof(TYPE), ...)
are replaced with:	kmalloc_obj(TYPE, ...)

Array allocations:	kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with:	kmalloc_objs(TYPE, COUNT, ...)

Flex array allocations:	kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with:	kmalloc_flex(*PTR, FAM, COUNT, ...)

(where TYPE may also be *VAR)

The resulting allocations no longer return "void *", instead returning
"TYPE *".

For NXP NCI devices (e.g. PN7150), the interrupt is level-triggered and
active high, not edge-triggered.

Using IRQF_TRIGGER_RISING in the driver can cause interrupts to fail
to trigger correctly.

Remove IRQF_TRIGGER_RISING and rely on the IRQ trigger type configured
via Device Tree.

This reverts commit 068648aab72c9ba7b0597354ef4d81ffaac7b979.

NFC packets may have NUL-bytes. Checking for string length is not a correct
assumption here. As long as there is a check for the length copied from
copy_from_user, all should be fine.

The fix only prevented the syzbot reproducer from triggering the bug
because the packet is not enqueued anymore and the code that triggers the
bug is not exercised.

The fix even broke
testing/selftests/nci/nci_dev, making all tests there fail. After the
revert, 6 out of 8 tests pass.
