utils: Fix BIT() to support up to 64 bits on all architectures 

devlink and vdpa use BIT() together with 64-bit flag fields.  devlink
is already using bit numbers greater than 31 and so does not work
correctly on 32-bit architectures.

Fix this by making BIT() use uint64_t instead of unsigned long.
