[U-Boot] pedantic cleanup -- sure is a lot of "#if 0" out there :-)

[Robert P. J. Day]

  another observation -- noticed "#if 0" in a header file i'm working
with, so did a quick grep from the top:

  $ grep -r "^#if 0" * | wc -l
  223
  $

and, what the heck:

  $ grep -r "^#if 1" * | wc -l
  37
  $

so after next release, i might rummage around in that and submit
patches, particularly when i see stuff like:


#if 0   /* already in asm/8xx_immap.h */
#define TBSCR_REFA      0x0080          /* Reference Interrupt Status A         */
#define TBSCR_REFB      0x0040          /* Reference Interrupt Status B         */
#define TBSCR_REFAE     0x0008          /* Second Interrupt Enable A            */
#define TBSCR_REFBE     0x0004          /* Second Interrupt Enable B            */
#define TBSCR_TBF       0x0002          /* Time Base Freeze                     */
#define TBSCR_TBE       0x0001          /* Time Base Enable                     */
#endif

/*-----------------------------------------------------------------------
 * PISCR - Periodic Interrupt Status and Control Register               11-31
 */
#undef  PISCR_PIRQ                      /* TBD                                  */
#define PISCR_PITF      0x0002          /* Periodic Interrupt Timer Freeze      */
#if 0   /* already in asm/8xx_immap.h */
#define PISCR_PS        0x0080          /* Periodic interrupt Status            */
#define PISCR_PIE       0x0004          /* Periodic Interrupt Enable            */
#define PISCR_PTE       0x0001          /* Periodic Timer Enable                */
#endif

  after all, if you have a comment that helpfully states that that
content is #if 0'ed out because it's already elsewhere, then (after
confirming that it is), that seems like a good candidate for deletion.

  all in good time ...
