This adds a pair of context save/restore functions to save/restore the state of a set of pinctrl registers. The context is lost during rtc only suspend with ddr in self-refresh on am43xx. Currently the save/restore is being done unconditionally. This will be optimized later with a pdata-quirk function which will allow is to save/restore only when doing the rtc only mode with ddr in self refresh.

I was debugging some gpio issues and I thought that the output of gpio debugfs was telling me the high or low level of the gpios with a '1' or a '0'. We saw a line like this though: gpio93 : in 4 2mA pull down and I started to think that there may be a gas leak in the building because '4' doesn't mean high or low, and other pins said '0' or '1'. It turns out, '4' is the function selection for the pinmux of the gpio and not the value on the pin. Reading code helps decipher what debugfs is actually saying. Add support to read the input or output pin depending on how the pin is configured so we can easily see the high or low value of the pin in debugfs. Now the output looks like gpio93 : in low func4 2mA pull down which clearly shows that the pin is an input, low, with function 4 and a 2mA drive strength plus a pull down.

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.
