The current SPCR code does not check the access width of the MMIO, and
uses a default of 8bit register accesses. This prevents devices that
only do 16 or 32bit register accesses from working. By simply checking
this field and setting the MMIO string appropriately, this issue can be
corrected. To prevent any legacy issues, the code will default to 8bit
accesses if the value is anything but 16 or 32.

Pull spi updates from Mark Brown:
"There's only one big change in this release but it's a very big
change: Geert Uytterhoeven has implemented support for SPI slave mode.
This feature has been on the cards since the subsystem was originally
merged back in the mists of time so it's great that Geert stepped up
and finally implemented it.
- SPI slave support, together with wholesale renaming of SPI
controllers from master to controller which went surprisingly
smoothly. This is already used with Renesas SoCs and support is in
the works for i.MX too.
- New drivers for Meson SPICC and ST STM32"

was moved. There were two problems with this. The first being that
i2c_pca_pf_resetchip was only used if platform data was provided. The
second that it was unconditionally overridden with
i2c_pca_pf_dummyreset. Ensure that however the reset gpio is defined the
correct reset_chip function is used.

ACPI video devices get tagged by the kernel with the custom LNXVIDEO
HID so that normal pnp-id matching can be used and are handled by the
acpi-video driver.
Sometimes the ACPI nodes describing these contain a SERIAL_TYPE_I2C ACPI
resource. Before this commit the presence of this resource would cause the
i2c-core to create a /sys/bus/i2c/devices/i2c-LNXVIDEO:00 device for this
with a modalias of: "i2c:LNXVIDEO:00".
There is no i2c driver for this custom HID, the acpi-video driver binds
directly to the ACPI device /sys/bus/acpi/devices/LNXVIDEO\:00 which has
a modalias of "acpi:LNXVIDEO:" .
Not only is the creation of an i2c-client for this undesirable, it is
actually causing problems. This weird pseudo-resource claims an i2c
speed of 100KHz and typically points to the i2c bus which is used by the
touchscreen controller. Some touchscreen controllers only work properly at
400KHz, at 100KHz they cause errors like these:
i2c_designware 80860F41:03: i2c_dw_handle_tx_abort: lost arbitration
i2c_designware 80860F41:03: i2c_dw_handle_tx_abort: lost arbitration
i2c_designware 80860F41:03: i2c_dw_handle_tx_abort: lost arbitration
i2c_designware 80860F41:03: i2c_dw_handle_tx_abort: lost arbitration
silead_ts i2c-MSSL1680:00: Registers clear error -11
This commit makes the i2c-core ignore LNXVIDEO compatible ACPI devices
which has 2 positive results:
1) The bogus i2c-client for these is no longer created.
2) i2c_acpi_lookup_speed now ignores the 100KHz speed from the pseudo
i2c-resouce and properly returns 400KHz as speed for the touchscreen
i2c bus, fixing the touchscreen not working on various devies.

We might have more/less queues once we reconnect/reset. For
example due to cpu going online/offline or controller constraints.

Its what the user passed, so its probably a better
idea to keep it intact. Also, limit the number of
I/O queues to max online cpus and the lport maximum
hw queues.
