At over 4000 #includes, <linux/platform_device.h> is the 9th most
#included header file in the Linux kernel. It does not need
<linux/mod_devicetable.h>, so drop that header and explicitly add
<linux/mod_devicetable.h> to source files that need it.
4146 #include <linux/platform_device.h>
After this patch, there are 225 files that use <linux/mod_devicetable.h>,
for a reduction of around 3900 times that <linux/mod_devicetable.h>
does not have to be read & parsed.
225 #include <linux/mod_devicetable.h>
This patch was build-tested on 20 different arch-es.
It also makes these drivers SubmitChecklist#1 compliant.

UniPhier SoCs have the following pins for hardware flow control of UART:
XRTS, XCTS
and for modem control of UART:
XDTR, XDSR, XDCD, XRI
The port number with the flow control is SoC-dependent.

This is handled by the mmc-pwrseq-emmc driver, which controls
an eMMC hardware reset via a GPIO line.
Remove it from the function pin-mux settings.

Save registers lost in the sleep when suspending, and restore them

For LD11/20 SoCs (capable of per-pin input enable), the iectrl bit
number matches its pin number. So, this is redundant information.
Instead, we just need a flag to know if the iectrl gating exists or not.
With this refactoring, 5 bits in pin data will be saved.

There are a bunch of GPIO muxing data, but most of them are actually
unneeded because GPIO-to-pin mapping can be specified by "gpio-ranges"
DT properties.
Tables that contain a set of GPIO pins are still needed for the named
mapping by "gpio-ranges-group-names". This is a much cleaner way for
UniPhier SoC family where GPIO numbers are not straight mapped to pin
numbers.

At first these drivers were written as tristate, but the module
usecases are actually not tested. Make all of them boolean.
