[PATCH] Bluetooth: btmtk: hide unused btmtk_mt6639_devs[] array

[Arnd Bergmann]

From: Arnd Bergmann <arnd at arndb.de>

When USB support is disabled, the array is not referenced anywhere,
causing a warning:

drivers/bluetooth/btmtk.c:35:3: error: 'btmtk_mt6639_devs' defined but not used [-Werror=unused-const-variable=]
   35 | } btmtk_mt6639_devs[] = {
      |   ^~~~~~~~~~~~~~~~~

Move it into the #ifdef block.

Fixes: 4cdd001ff03f ("Bluetooth: btmtk: Add MT6639 (MT7927) Bluetooth support")
