This patch adds the support of I2C_SMBUS_I2C_BLOCK_DATA transaction type
for the stm32f7 SMBUS Controller.
Use emulated I2C_SMBUS_I2C_BLOCK_DATA transactions as there is no specific
hardware in STM32 I2C to manage this (e.g. like no need for PEC here).
Emulated transfer will fall back calling i2c transfer method where there's
already support for DMAs for example.
So, use the I2C_FUNC_SMBUS_I2C_BLOCK in stm32f7_i2c_func(), and rely on
emulated transfer by returning -EOPNOTSUPP in the smbus_xfer() routine
for such a case.

i2c/for-5.3
I realize that there are changes in drivers/i2c/busses/i2c-i801.c that strictly
speaking don't belong here, but I hope you don't mind. These changes are all
about the interaction with the i2c-mux-gpio code, and I did a test-merge a few
days ago w/o conflicts.
Anyway, the GPIO-work from Linus Walleij (with help from Serge Semin) in the
i2c-mux-gpio and i2c-arb-gpio-challenge drivers is the main feature.

Sometimes the register status can include interrupts that
were masked. We can, for example, get the RF-Kill bit set
in the interrupt status register although this interrupt
was masked. Then if we get the ALIVE interrupt (for example)
that was not masked, we need to *not* service the RF-Kill
interrupt.
Fix this in the MSI-X interrupt handler.

Newest devices have a new firmware load mechanism. This
mechanism is called the context info. It means that the
driver doesn't need to load the sections of the firmware.
The driver rather prepares a place in DRAM, with pointers
to the relevant sections of the firmware, and the firmware
loads itself.
At the end of the process, the firmware sends the ALIVE
interrupt. This is different from the previous scheme in
which the driver expected the FH_TX interrupt after each
section being transferred over the DMA.
In order to support this new flow, we enabled all the
interrupts. This broke the assumption that we have in the
code that the RF-Kill interrupt can't interrupt the firmware
load flow.
Change the context info flow to enable only the ALIVE
interrupt, and re-enable all the other interrupts only
after the firmware is alive. Then, we won't see the RF-Kill
interrupt until then. Getting the RF-Kill interrupt while
loading the firmware made us kill the firmware while it is
loading and we ended up dumping garbage instead of the firmware
state.
Re-enable the ALIVE | RX interrupts from the ISR when we
get the ALIVE interrupt to be able to get the RX interrupt
that comes immediately afterwards for the ALIVE
notification. This is needed for non MSI-X only.

We added code to restock the buffer upon ALIVE interrupt
when MSI-X is disabled. This was added as part of the context
info code. This code was added only if the ISR debug level
is set which is very unlikely to be related.
Move this code to run even when the ISR debug level is not
set.
Note that gen2 devices work with MSI-X in most cases so that
this path is seldom used.

In AP (and IBSS) mode, we can only set GTKs to firmware after we have
sent down the multicast station, but this we can only do after we've
enabled beaconing, etc.
However, during rfkill exit, hostapd will configure the keys before
starting the AP, and cfg80211/mac80211 accept it happily.
On earlier devices, this didn't bother us as GTK TX wasn't really
handled in firmware, we just put the key material into the TX cmd
and thus it only mattered when we actually transmitted a frame.
On newer devices, however, the firmware needs to track all of this
and that doesn't work if we add the key before the (multicast) sta
it belongs to.
To fix this, keep a list of keys to add during AP enable, and call
the function there.

In some buggy scenarios we could possible attempt to transmit frames larger
than maximum MSDU size. Since our devices don't know how to handle this,
it may result in asserts, hangs etc.
This can happen, for example, when we receive a large multicast frame

Since in a legal scenario this should never happen, drop such frames and
warn about it.
