[PATCH v4 17/79] include/uapi/sound/emu10k1.h: added EMU10K1 version of DECLARE_BITMAP macro

[Mikko Rapeli]

Fixes userspace compilation error:

error: expected specifier-qualifier-list before âDECLARE_BITMAPâ
  DECLARE_BITMAP(gpr_valid, 0x200); /* bitmask of valid initializers */

DECLARE_BITMAP macro is not meant for userspace headers and thus
added here as private copy for emu10k.h.

Fix was suggested by Arnd Bergmann <arnd@xxxxxxxx> in message
<2168807.4Yxh5gl11Q@wuerfel> and Takashi Iwai <tiwai@xxxxxxx>
in message <s5h1thx88tk.wl-tiwai@xxxxxxx> on lkml.
