tools/boot/noble: Switch ubuntustudio to generic kernel
Starting with Plucky (and hence hwe-6.14) the lowlatency kernel is the generic kernel with some bootargs to make it lowlatency. Going forwar, there is no lowlatency flavor anymore. This commit fixes only Noble for the upcoming .3 point release. Plucky and Questing come later... Signed-off-by: Juerg Haefliger <[email protected]>
