This change will make it so the standard rdev readat call will use the

There is a magic bit that needs to be set for the SPI DMA controller to

The configuration of the setting `chipset_lockdown` doesn't have any
effect for most of the variants since their configuration of
`common_soc_config` overwrites the configuration of the baseboard's
devicetree. If `chipset_lockdown` is configured separately in the
baseboard devicetree, the variant overridetrees reuse its
configuration.
Thus, move `chipset_lockdown` out of `common_soc_config` in the
baseboard devicetree and configure it separately.

The patch adds an interface for configuring GPIOs inside the Kontron
CPLD/EC. This allows to statically define the mode for each GPIO pin
in devicetree.cb of the motherboard or carrier board. For example:
chip ec/kontron/kempld
device gpio 0 on
register "gpio[0]" = "KEMPLD_GPIO_INPUT"
register "gpio[4]" = "KEMPLD_GPIO_OUTPUT_LOW"
register "gpio[5]" = "KEMPLD_GPIO_OUTPUT_HIGH"
register "gpio[11]" = "KEMPLD_GPIO_DEFAULT"
end
end
In this case, <device gpio 0>, like all other devices, is not a real
device inside the EC. These definitions are used to understand the EC
resources and systematize configuration options, but if mark this as
<off>, the initialization step will be skipped in the driver code.
Use KEMPLD_GPIO_DEFAULT or skip it in devicetree.cb to not configure
the GPIO and keep the default mode after CPLD reset.
This work is based on code from the drivers/gpio/gpio-kempld.c linux
driver. Tested on Kontron mAL-10 COMe module [1].

The Fast Read Dual Output and Fast Read Dual I/O commands are
practically identical, the only difference being how the read address is
transferred (saving a whooping 2 bytes which is totally irrelevant for
the amounts of data coreboot tends to read). We originally implemented
Fast Read Dual Output since it's the older command and some older
Winbond chips only supported that one... but it seems that some older
Macronix parts for whatever reason chose to only support Fast Read Dual
I/O instead. So in order to make this work for as many parts as
possible, I guess we'll have to implement both. (Also, the Macronix
device ID situation is utter madness with different chips with different
capabilities often having the same ID, so we basically have to make a
best-effort guess to strike a trade-off between fast speeds and best
chance at supporting all chips. If this turns out to be a problem later,
we may have to add Kconfig overrides for this or resort to SFDP parsing,
although that would defeat the whole point of trying to be fast.)
