convert to DM_I2C for U-Boot while leaving SPL legacy I2C:
- Move I2C config from common to SPL
- Move PMIC config from common to SPL (no need to re-configure pmic)
- add DM_I2C support to eeprom/gsc functions shared by SPL and U-Boot

commit 7c84319af9c7 ("dm: gpio: Correct use of -ENODEV in drivers")
changed the return code for an I2C NAK from -ENODEV to -EREMOTEIO.
Update the gsc_i2c_read and gsc_i2c_write functions for this change
to properly retry the transaction on a NAK meaning the GSC is busy.

We should not use typedefs in U-Boot. They cannot be used as forward
declarations which means that header files must include the full header to
access them.
Drop the typedef and rename the struct to remove the _s suffix which is
now not useful.
This requires quite a few header-file additions.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

The command can only be used from full U-Boot, so do not build it into

The Gateworks System Controller on Ventana boards has the ability to
disable the board's primary power supply until the RTC hits a specific
time. When sleeping a button-down event on the GSC user pushbutton will
wake the board before it's wake time has been reached. This feature is
referred to as GSC sleep.
Add a command to invoke sleep mode for a specified number of seconds.

This adds information about the Gateworks System Controller to the gsc command
such as the firmware version, firmware CRC and status of the GSC watchdog
(if its enabled and if its tripped).
Additionally the 'gsc wd' command can be used to enable or disable the
watchdog with the following usage:
gsc wd enable [30|60]
gsc wd disable
Note that the GSC registers are battery-backed by the GSC coincell so once
eanbled, they remain enabled across power-cycles or until either the GSC
firmware has been updated or FLASH has been re-programmed by the Gateworks
JTAG adapter.
