gpu: nvgpu: fix circular dep of ce2 and gk20a headers

Browse Source 
struct gk20a from gk20a.h needs defination of struct gk20a_ce_app
and ce2_gk20a.h needs defination of struct gk20a. This creates
a circular dependency.

Fix this by making gk20a_ce_app a pointer to skip knowing the
complete type details and using forward declarations for struct
gk20a_ce_app and struct gk20a.

The gk20a_ce_app pointer is alloc'ed in gk20a_init_ce_support()
and free'ed in gk20a_ce_destroy.
