gpu: nvgpu: ACR code refactor
-Created struct nvgpu_acr to hold acr module related member within single struct which are currently spread across multiple structs like nvgpu_pmu, pmu_ops & gk20a. -Created struct hs_flcn_bl struct to hold ACR HS bootloader specific members -Created struct hs_acr to hold ACR ucode specific members like bootloader data using struct hs_flcn_bl, acr type & falcon info on which ACR ucode need to run. -Created acr ops under struct nvgpu_acr to perform ACR specific operation, currently ACR ops were part PMU which caused to have always dependence on PMU even though ACR was not executing on PMU. -Added acr_remove_support ops which will be called as part of gk20a_remove_support() method, earlier acr cleanup was part of pmu remove_support method. -Created define for ACR types, -Ops acr_sw_init() function helps to set ACR properties statically for chip currently in execution & assign ops to point to needed functions as per chip. -Ops acr_sw_init execute at early as nvgpu_init_mm_support calls acr function to alloc blob space. -Created ops to fill bootloader descriptor & to patch WPR info to ACR uocde based on interfaces used to bootstrap ACR ucode. -Created function gm20b_bootstrap_hs_acr() function which is now common HAL for all chips to bootstrap ACR, earlier had 3 different function for gm20b/gp10b, gv11b & for all dgpu based on interface needed. -Removed duplicate code for falcon engine wherever common falcon code can be used. -Removed ACR code dependent on PMU & made changes to use from nvgpu_acr.
