gpu: nvgpu: initialze bundle64 state

We receive bundle with address and 64 bit values from ucode on some platforms
This patch adds the support to handle 64 bit values

Add struct av64_gk20a to store an address and corresponding 64 bit value
Add struct av64_list_gk20a to store count and list of av64_gk20a

Add API alloc_av64_list_gk20a() to allocate the list that supports 64bit
values

In gr_gk20a_init_ctx_vars_fw(), if we see NETLIST_REGIONID_SW_BUNDLE64_INIT,
load the bundle64 state into above local structures

Add new HAL gops.gr.init_sw_bundle64() and call it from gk20a_init_sw_bundle()
if defined

Also load the bundle for simulation cases in gr_gk20a_init_ctx_vars_sim()
