[U-Boot] [PATCH 03/10] Kconfig: add CONFIG_BOOTDELAY

[Igor Grinberg]

Add CONFIG_BOOTDELAY to the Kconfig.
To make the transition easier, we define CONFIG_AUTOBOOT_BOOTDELAY to
actually enable the CONFIG_BOOTDELAY Kconfig setting.
Once all boards finish transitioning to Kconfig, we can remove the
CONFIG_AUTOBOOT_BOOTDELAY and just leave the CONFIG_BOOTDELAY unguarded.
