[PATCH 1/3] Input: add `SW_BOOT_ALT`

[Quentin Schulz]

From: Quentin Schulz <quentin.schulz@xxxxxxxxxxxxxxxxxxxxx>

This event code represents the firmware source to use at boot.
Value 0 means using "standard" firmware source, value 1 means using
"alternative" firmware source.

For example, some hardware has the ability to force the BOOTROM to load
the bootloader from a secondary firmware source (say SD card) instead of
trying with the standard first and then the secondary. This event allows
the userspace to know which firmware source was requested *in hardware*.
