SPDX: Convert all of our single license tags to Linux Kernel style 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. Signed-off-by: Tom Rini <trini@konsulko.com>

sunxi: axp: Move axp gpio code to a separate axpi-gpio driver Move the axp-gpio code out of the drivers/power/axp*.c code, and into a new separate axpi-gpio driver. This change drops supports for the gpio3 pin on the axp209, as that requires special handling, and no boards are using it. Besides cleaning things up by moving the code to a separate driver, as a bonus this change also adds support for the (non vusb) gpio pins on the axp221 and the gpio pins on the axp152. The new axp-gpio driver gets its own Kconfig option, and is only enabled on boards which need it. Besides that it only gets enabled in the regular u-boot build and not for the SPL as we never need it in the SPL.

/* For axp_gpio.c */
include: axp_pmic: Include headers for all variants A single DM-based driver should be able to support some feature for several PMIC variants where the interface is the same. For example, all PMIC variants use the same register bit to trigger poweroff. However, currently only definitions for a single PMIC are available at a time. This requires drivers to use #ifdefs and different indentifiers for each variant they support. Let's simplify this by making register definitions for all variants available from the header. Then no preprocessor conditions are needed; the driver can use the register definition from any variant that supports the relevant feature. An exception is the GPIO-related definitions, which do not use unique identifiers. So for now, keep them like before. They will be cleaned up along with the GPIO driver.

pmic: axp: define ALDO_IN startup bit Most AXP PMICs feature a "startup source" register, which keeps information about how the PMIC started operation. Bit 0 in there means it has been started by "plugging in the power cable". Define a symbol in each PMIC's header file to be able to use that register and bit later on.
