Vedashree Vidwans 8d325e9db1 gpu: nvgpu: re-architect nvgpu allocator functions
Currently, buddy, page and bitmap allocators have individual init()
functions. This patch creates common nvgpu_alloc_allocator_init()
function to trigger the individual functions based on allocator type
argument. This makes writing requirements for the allocators easier.

Jira NVGPU-991
