After this patch the mxs_gpio.c DM/DTS driver can be used at early SPL to
read states of gpio pins (and for example alter the boot flow).
It was necessary to adjust its name to 'fsl_imx_2{38}_gpio' to match
requirements for SPL_OF_PLATDATA usage.

At present there is only one control for this and it is used for both SPL
and TPL. But SPL might have a lot more space than TPL so the extra cost of
a full printf() might be acceptable.
Split the option into two, providing separate SPL and TPL controls. The
TPL setting defaults to the same as SPL.

commit 1b898ffc040b ("gpio: dwapb_gpio: convert to livetree") introduced
a bug in that dev->node of the gpio chip was accidentally set to the
of_node of its bank subnode.
What it meant to do was assign subdev->node, not dev->node.
While this doesn't affect too many use cases, iterating over the gpio
chip's properties doesn't work any more after that, so fix this.

Currently mach-mt7620 contains only support for mt7628. To avoid confusion,
rename mach-mt7620 to mach-mtmips, which means MediaTek MIPS platforms.
MT7620 and MT7628 should be distinguished by SOC_MT7620 and SOC_MT7628
because they do not share the same lowlevel codes.
Dependencies of four drivers are changed to SOC_MT7628 as these drivers
are only used by MT7628.

This add support for the the MSCC serial GPIO driver in MSCC
VCoreIII-based SOCs.
By using a serial interface, the SIO controller significantly extends
the number of available GPIOs with a minimum number of additional pins
on the device. The primary purpose of the SIO controller is to connect
control signals from SFP modules and to act as an LED controller.
This adds the base driver.

The VCore III SoCs such as the Luton but also the Ocelot can remap an SPI
flash directly in memory. However, for writing in the flash the
communication has to be done by software.
Each of the signal used for the SPI are exposed in a single register. In
order to be able to use the soft-spi driver, the management of this pin
is done through this simple gpio driver.
Even if the main purpose of this driver is to be used by soft-spi, it can
still be used as a normal gpio driver but with limitation: for example
the first pin can't be used as output.

In some STM32 SoC packages, GPIO bank has not always 16 gpios.
Several cases can occur, gpio hole can be located at the beginning,
middle or end of the gpio bank or a combination of these 3
configurations.
For that, gpio bindings offer the gpio-ranges DT property which
described the gpio bank mapping.

As a preparation for merging the socfpga gen5 devicetree files
from Linux, this patch makes the dwapb gpio driver work correctly
without the 'bank-name' property on the gpio-controller nodes.
This property is not present in the Linux drivers and thus is not
present in the Linux devicetrees. It is only used to access pins
via bank name.
This fallback is necessary since without it, the driver will
return an error code which will lead to an error in U-Boot
startup.
The bank names will still be added to the default board device
trees in follow-up patch, but other boards using this driver and
not including the bank name should also work with the socfpga.dtsi
without adding the bank-name property.

The pca953x_gpio driver uses default value of polarity inversion
register. For some devices like PCA9557 and MAX7310, their polarity
inversion register default value is 0xf0. So for high 4 ports, when
reading their values, the values are inverted as the actual level.
This patch clears the polarity inversion register to 0 at init, so
that the port read and write values are aligned.

When a driver declares DM_FLAG_PRE_RELOC flag, it wishes to be
bound before relocation. However due to a bug in the DM core,
the flag only takes effect when devices are statically declared
via U_BOOT_DEVICE(). This bug has been fixed recently by commit
"dm: core: Respect drivers with the DM_FLAG_PRE_RELOC flag in
lists_bind_fdt()", but with the fix, it has a side effect that
all existing drivers that declared DM_FLAG_PRE_RELOC flag will
be bound before relocation now. This may expose potential boot
failure on some boards due to insufficient memory during the
pre-relocation stage.
To mitigate this potential impact, the following changes are
implemented:
- Remove DM_FLAG_PRE_RELOC flag in the driver, if the driver
only supports configuration from device tree (OF_CONTROL)
- Keep DM_FLAG_PRE_RELOC flag in the driver only if the device
is statically declared via U_BOOT_DEVICE()
- Surround DM_FLAG_PRE_RELOC flag with OF_CONTROL check, for
drivers that support both statically declared devices and
configuration from device tree
