This migrates the last user of the legacy LED API, IMX233-OLinuXino, to the modern LED framework. The current implementation does the following: - lit the LED when booting, - turn off the LED the moment a BOOTP packet is received, The first step is easily reproduced by using the /options/u-boot/boot-led property to point at the LED. Unfortunately, the boot-led is only lit by U-Boot proper at the very end of the boot process, much later than currently. We can however force the LED on whenever the GPIO LED driver is bound by marking the LED as default-state = "on", and this happens slightly before board_init() is called. We then do not need /options/u-boot/boot-led property for that anymore. However, the second step relies on /options/u-boot/boot-led and CONFIG_LED_BOOT being set to reproduce the same behavior and requires us to migrate net/bootp.c to the modern LED framework at the same time to keep bisectability. I couldn't figure out how to map CONFIG_LED_STATUS_BIT=778 to an actual GPIO on the SoC but according to the schematics[1] only one LED is present. I couldn't also map the SoC pin number to an actual GPIO from the IMX23 manual, but there's already one GPIO LED specified in the Device Tree so my guess is all of those are one and the same. This was only build tested as I do not own this device.
