The pinctrl-mcp23s08 driver doesn't provide a specific gpiospec
of_xlate() function, causing the gpiolib-of's of_gpio_simple_xlate()
function to be used instead, which takes the gpiospec's second cell as
the flags specifier according to 'include/dt-bindings/gpio/gpio.h'.

The pinctrl-mcp23s08 bindings document was mentioning that the flags
were unused, which is not accurate because values in that second cell
are indeed used by the gpiolib-of's of_gpio_simple_xlate() for
configuring the gpio (e.g. its polarity).

This way, replace the "flags currently unused" reference in the
dt-bindings document with references to the appropriate files specifying
the possible flag values and gpiospec description.

Newer versions of the firmware for the Qualcomm Datacenter Technologies
QDF2400 restricts access to a subset of the GPIOs on the TLMM.  To
prevent older kernels from accidentally accessing the restricted GPIOs,
we change the ACPI HID for the TLMM block from QCOM8001 to QCOM8002,
and introduce a new property "gpios".  This property is an array of
specific GPIOs that are accessible.  When an older kernel boots on
newer (restricted) firmware, it will fail to probe.

To implement the sparse GPIO map, we register all of the GPIOs, but
fill in the data only for available GPIOs.  This ensures that the driver
cannot accidentally access an unavailable GPIO.

The pinctrl-msm driver also scans the "gpios" property to determine
which pins are available, and ensure that only those can be registered.

Support for QCOM8001 is removed as there is no longer any firmware that
implements it.
