configs/beagleboneai_defconfig: move to u-boot 2021.04 / mainline linux 5.10.79 This board is now supported by mainline u-boot and Linux. For U-Boot we unfortunately still need a patch as the available (<rev A2) boards do not have an identification eeprom, causing boot failures. Use the workaround patch by Robert Nelson also used by the official bb.org builds. Signed-off-by: Peter Korsgaard <peter@korsgaard.com>
