mlxbf-bootctl: fix the build error with FIELD_PREP()

rsh_log_store() calls the FIELD_PREP() macro without including the
required header file, resulting a build error:

  CC      drivers/platform/mellanox/mlxbf-bootctl.o
drivers/platform/mellanox/mlxbf-bootctl.c: In function ‘rsh_log_store’:
drivers/platform/mellanox/mlxbf-bootctl.c:429:16: error: implicit declaration of function ‘FIELD_PREP’ [-Wimplicit-function-declaration]
  429 |         data = FIELD_PREP(MLXBF_RSH_LOG_TYPE_MASK, MLXBF_RSH_LOG_TYPE_MSG);
      |                ^~~~~~~~~~

Fix this by including the <linux/bitfield.h> file.
