gpu: nvgpu: create common.fbp unit

Browse Source 
create a new unit common.fbp which initializes fbp support and provides
APIs to retrieve fbp data.

Create private header with below data
struct nvgpu_fbp {
        u32 num_fbps;
        u32 max_fbps_count;
        u32 fbp_en_mask;
        u32 *fbp_rop_l2_en_mask;
};

Expose below public APIs to initialize/remove fbp support:
nvgpu_fbp_init_support()
nvgpu_fbp_remove_support()
vgpu_fbp_init_support() for vGPU

Expose below APIs to retrieve fbp data
nvgpu_fbp_get_num_fbps()
nvgpu_fbp_get_max_fbps_count()
nvgpu_fbp_get_fbp_en_mask()
nvgpu_fbp_get_rop_l2_en_mask()

Use above APIs to retrieve fbp data in all the code.

Remove corresponding fields from struct nvgpu_gr since they are no
longer referred from that structure
