staging: ste_rmi4: avoid unused function warnings

The rmi4 touchscreen driver encloses the power-management
functions in #ifdef CONFIG_PM, but the smtcfb_pci_suspend/resume
functions are only really used when CONFIG_PM_SLEEP is also
set, as a frequent gcc warning shows:

ste_rmi4/synaptics_i2c_rmi4.c:1050:12: warning: 'synaptics_rmi4_suspend' defined but not used
ste_rmi4/synaptics_i2c_rmi4.c:1084:12: warning: 'synaptics_rmi4_resume' defined but not used

This changes the driver to remove the #ifdef and instead mark
the functions as __maybe_unused, which is a nicer anyway, as it
provides build testing for all the code in all configurations
and is harder to get wrong.

staging: octeon: Fix logic for waking octeon ethernet tx queue.

Only wake tx queue when driver queue is back within bounds.

The logic here was just reenabling the queue when any buffers had been
freed.  the queue was stopped whenever the length exceeded 1000
(MAX_OUT_QUEUE_DEPTH), but then was essentially immediately started again.
On a congested link, the queue length would just keep increasing up to
around 8000 (for average size packets), at which point the hardware would
start refusing the packets and they would begin to be dropped.
This prevented the qdisc layer from effectively managing and prioritising
packets, as essentially all packets were being allowed into the driver
queue and then were being dropped by the hardware.

This change only restarts the queue if the length is less than 1000
(MAX_OUT_QUEUE_DEPTH).

staging: octeon-ethernet: fix TCP/UDP checksum calc

If the network portion of a frame is preceded by more than 14 bytes of
data, the checksum calculated in the HW is done over the wrong data and
is put in the wrong place.
In our use case an Octeon ethernet controller is connected to a Broadcom
switch chip. Extra data is included in the frame prior to egressing the
Octeon ethernet (i.e. 4 bytes of an 802.1Q tag, 4 bytes of a proprietary
BCM tag later stripped by the switch chip). This extra data causes the
checksum calculation to be incorrect.
The fix in this patch is to make use of the network header offset of the
skb. This enables the checksum to be calculated correctly.
This has been tested in both the configuration with the switch chip in
the egress path (as described above) and in a simple connection direct
to the wire.

staging: fsl-mc: Extended MC bus allocator to include IRQs

All the IRQs for DPAA2 objects in the same DPRC must use
the ICID of that DPRC, as their device Id in the GIC-ITS.
Thus, all these IRQs must share the same ITT table in the GIC.
As a result, a pool of IRQs with the same device Id must be
preallocated per DPRC (fsl-mc bus instance). So, the fsl-mc
bus object allocator is extended to also provide services
to allocate IRQs to DPAA2 devices, from their parent fsl-mc bus
IRQ pool.
