alarm/uboot-raspberrypi to 2024.07-4

Fix an issue where u-boot would hang whenever a device (for
example the GPS hat from Adafruit) is connected to the RPi's
GPIO header.

These devices usually output something to the serial console
during the startup phase of u-boot, making u-boot think it has
to interrupt its boot sequence because somebody is trying to
interrupt its startup.

Closes #2053

Run-tested: RPi4B
