    pistachio: switch to 5.15 by default
    
    It appears that only a few users are using the pistachio SoC. The most
    active user of the target has already approved the testing kernel and
    so it is very unlikely bugs will be reported in the near future.
    Therefore, the target should be directly bumped to 5.15.
