Setting F2 block size to 128 bytes for BCM4329 allows to significantly
improve RX throughput on NVIDIA Tegra20. Before this change the throughput
was capped to 30 Mbit/s on Tegra, now throughput is at 40 Mbit/s, which is
a maximum throughput for the BCM4329 chip. The F2 block size is borrowed
from the downstream BCMDHD driver. The comment in the BCMDHD driver says
that 128B improves throughput and turns out that it works for the brcmfmac
as well.

This patch fixes SDHCI CRC errors during of RX throughput testing on
BCM4329 chip if SDIO BUS is clocked above 25MHz. In particular the
checksum problem is observed on NVIDIA Tegra20 SoCs. The good watermark
value is borrowed from downstream BCMDHD driver and it's matching to the
value that is already used for the BCM4339 chip, hence let's re-use it
for BCM4329.

Clang static analysis reports this error
brcmfmac/core.c:490:4: warning: Dereference of null pointer

^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
In this block of code
if (ret || !(*ifp) || !(*ifp)->ndev) {
if (ret != -ENODATA && *ifp)
(*ifp)->ndev->stats.rx_errors++;
brcmu_pkt_buf_free_skb(skb);
return -ENODATA;
}
(*ifp)->ndev being NULL is caught as an error
But then it is used to report the error.
So add a check before using it.

The code in the BRCM80211 BRCMSMAC driver is using the legacy
GPIO API to to a complex check of the validity of the base of
the GPIO chip and whether it is present at all and then adding
an offset to the base of the chip.
Use the existing function to obtain a GPIO line internally
from a GPIO chip so we can use the offset directly and
modernize the code to use GPIO descriptors instead of integers
from the global GPIO numberspace.

The driver relies on the compatible string from DT to determine which
FW configuration file it should load. The DTS spec allows for '/' as
part of the compatible string. We change this to '-' so that we will
still be able to load the config file, even when the compatible has a
'/'. This fixes explicitly the firmware loading for
"solidrun,cubox-i/q".

Linux 3.6 introduces TSQ which has a per socket threshold for TCP Tx
packet to reduce latency. In flow control mode, host driver enqueues skb
in hanger and TCP doesn't push new skb frees until host frees the skb when
receiving fwstatus event. So set pacing shift 8 to send them as a single
large aggregate frame to the bus layer.

When USB or SDIO device got abnormal bus disconnection, host driver
tried to clean up the skbs in PSQ and TXQ (The skb's pointer in hanger
slot linked to PSQ and TSQ), so we should set the state of skb hanger slot
to BRCMF_FWS_HANGER_ITEM_STATE_FREE before freeing skb.
In brcmf_fws_bus_txq_cleanup it already sets
BRCMF_FWS_HANGER_ITEM_STATE_FREE before freeing skb, therefore we add the
same thing in brcmf_fws_psq_flush to avoid following warning message.
