      [ALSA] Revert "alsa: add annotations to bitwise type snd_pcm_hw_param_t" · eabe3228

      This reverts commit 36b34d2437104f323e09d7c6af6451d3c0b9c0cd.
      
      From: Al Viro <viro@ZenIV.linux.org.uk>
      
      WIW, *all* this stuff is not bitwise at all.  For crying out loud, half
      of these types are routinely used as array indices and loop variables...
      
      If anything, we want a different set of allowed operations - subtraction
      between elements of type (yielding integer), addition/subtraction of
      integer types not bigger than ours (yielding our type), comparisons,
      assignments (=, +=, -=, passing to function as argument, return from
      function, initializers) and second/third arguments in ?:.  With 0 *not*
      being allowed as a constant of such type.
      
      It's not bitwise; we may use the same infrastructure in sparse, but it
      should be a separate class of types (__attribute__((affine))).
      
      dma_addr_t is another candidate for the same treatment, but there we'll
      need helpers for conversions to hw-acceptable form (dma_to_le32(), etc.)
      and gradual conversion of drivers.
      
      ALSA ones and pm mess are absolutely straightforward cases, though.
