The network stack will take care to reserve space for HH_DATA_MOD when
building the skb, so there's no need to account for it in the netdevice
needed headroom. Based on that, decrease the frame buffer headroom for
ingress frames.

Instead of the old opaque value, define the Rx buffer headroom size
based on other frame buffer fields, in accordance to how we expect them
to be configured by MC.
Based on DPNI_BUF_LAYOUT_OPT_TIMESTAMP, MC will enable an additional
field in the Tx hardware annotation area, increasing its size to 128.
Update the driver value to reflect this.

With the introduction of PFC support, there are multiple ways taildrop
is configured, based on the DPNI pause frame configuration:
- no pause frames - per-queue taildrop thresholds.
- pause frames - no taildrop thresholds (pause frames sent based on
buffer depletion).
- PFC pause frames - per-group (traffic class) taildrop thresholds for
non-PFC enabled priorities (pause frames sent based on Rx congestion
notifications).
Refactor the fq taildrop setup area.

Add initial DCB ops in the DPAA2 Ethernet driver. Currently they are
dummy calls.
Tested integration with userspace lldpad:
- lldpad daemon running
- bring interface up
- lldptool -L -i niX adminStatus=rxtx
- lldptool -T -i niX -V PFC -c enabled={prio comma separated list}
- lldptool -t -i niX -V PFC -c enabled

The driver only handles frame workqueues associated with traffic class
0. Add support for multiple traffic classes for the same flowid, based
on the tc field in the fq struct, and the num_tcs parameter in the dpni
atttributes. Create a separate fq for each tc x flowid. Display the
information in debugfs.

Previous commits:
6e2387e8f19e ("staging: fsl-dpaa2/eth: Add Freescale DPAA2 Ethernet driver")
39163c0ce0f4 ("staging: fsl-dpaa2/eth: Errors checking update")
have added bits that are not specific to the WRIOP accelerator.
Move these where they belong (in DPIO) such that other accelerators
can make use of them.
While here, fix the values of FD_CTRL_FSE and FD_CTRL_FAERR, which
were shifted off by one bit.

Introduce the DPAA2 Ethernet driver, which manages Datapath
Network Interface (DPNI) objects discovered on the MC bus.
In addition to DPNIs, the Ethernet driver uses several other
MC objects to build a network interface abstraction: buffer
pools (DPBPs), I/O Portals (DPIOs) and concentrators (DPCONs).
The starting point is the SDK 2.0 GA 1703 driver, plus the following
changes:
- removed busy poll code (integrated into netstack)
- minor signature change for dpaa2_eth_get_stats
- debugfs support removed (contained into different patch)
- Tx queues registered to XPS
- max MTU handling changed according to netdevice update
- dropped dpaa2_sg_{le_to_cpu/cpu_to_le} - no longer needed
(BIG_ENDIAN support not tested yet)
