    common: asm/desc.h is an x86-only header
    
    From briefly going over 9062553a0dc1 it looks like the #include in what
    was ac_timer.c was added there for no reason. It's unneeded now in any
    event, and it is the sole reason for Arm to have that dummy header.
    Purge that, thus avoiding PPC (and later RISC-V) to also gain one.
