During the initialization of PHY the gigabit bit capable is set if the
controller is a GEM. However, for sama5d2 and sama5d4, the GEM is
configured to support only 10/100.
Improperly setting the GBE capability leads to an unresponsive MAC
controller. This patch fixes this behavior allowing using the gmac with
these SoCs.

At present this SPI driver works by searching the PCI buses for its
peripheral. It also uses the legacy PCI API.
In addition the driver has code to determine the type of Intel PCH that is
used (version 7 or version 9). Now that we have proper PCH drivers we can
use those to obtain the information we need.
While the device tree has a node for the SPI peripheral it is not in the
right place. It should be on the PCI bus as a sub-peripheral of the LPC
device.
Update the device tree files to show the SPI controller within the PCH, so
that PCI access works as expected.

USB protocol allows for 16 IN and 16 OUT endpoints (USB 2.0 Spec,
8.3.2.2 Endpoint Field). A function may have an EP 1 for both IN and OUT,
so these two should be kept separate. As EPs are either BULK or INTERRUPT
(or ISO), it is fine to have one array per direction for all transfer
types (also see e236519b73).
USB device address is 7 bits, so a bus may have more than 16 devices.
Check the device number, as the DWC2 driver only supports BULK/ISO for
the first 16 devices.

CSPLITs for INTERRUPT transactions have to be scheduled in each microframe
following the SSPLIT. INTERRUPT transfers are executed in the next even/
odd microframe depending on the HCCHAR_ODDFRM flag.
As there are no handshakes for INTERRUPT SSPLITs the SSPLIT may have
failed (transport error) without the error being detected by the host
driver. If the last CSPLIT is not received within 4 microframes after the
SSPLIT there was a transaction error and the complete transaction has
to be restarted.

Fix two errors in transfer len calculation, move loop invariant code out
of loop.
If xfer_len is equal to CONFIG_DWC2_MAX_TRANSFER_SIZE (or slightly
smaller), the xfer_len will be to large, e.g.:
xfer_len = MAX_TRANSFER_SIZE = 65535
max packet size = 512
=> num_packets = 128
=> IN xfer_len = 65536
For OUT transactions larger than (65536 - mps) bytes, the xfer_len
determination is quite awkward, it is only correct due to:
- max_packet_size for control/bulk/interrupt is required to be
power-of-two.
- (CONFIG_DWC2_MAX_TRANSFER_SIZE + 1) % max-packet-size is zero
for all allowed (2^3 ... 2^9) packet sizes
As the max xfer len is loop invariant, it can be moved out of the loop.
