Subject: [PATCH] nvadsp: t264: Add missing bits.h header
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

With Linux v6.13, the Tegra264 NVADSP driver fails to build and the
following errors are observed:

 In file included from drivers/platform/tegra/nvadsp/dev-t264.c:4:
  include/linux/reset.h:30:49: error: implicit declaration of function
  ‘BIT’ [-Werror=implicit-function-declaration]
   30 | #define RESET_CONTROL_FLAGS_BIT_ACQUIRED        BIT(2)
      |                                                 ^~~

 In file included from drivers/platform/tegra/nvadsp/dev-t264-aon.c:4:
  /include/linux/reset.h:30:49: error: implicit declaration of function
  ‘BIT’ [-Werror=implicit-function-declaration]
   30 | #define RESET_CONTROL_FLAGS_BIT_ACQUIRED        BIT(2)
      |                                                 ^~~

Fix this by adding the missing 'bits.h' header.
