[PATCH] alpha: misc fixes [9/10]

Set of small fixes:
- pcibios_init() must be int;
- fls() - ctlz on ev67, generic on others. This was required for
  something several kernel releases back, now it seems to be unused.
  Anyway, it shouldn't hurt, so included here.
- missing #includes, missing #if RTC_IRQ in drivers/char/rtc.c;
- define USER_HZ;
From Jeff Wiedemeier:
- rename alpha-specific config section 'General setup' to 'System setup'
  to avoid confusion with generic 'General setup';
- fix the 'bootpfile' build.
