This patch removes linux dependencies from sim_gk20a.h under gk20a/sim_gk20a.h. The following changes are made in this patch. 1) Created a linux based structure sim_gk20a_linux that contains a common sim_gk20a struct inside it. The common struct sim_gk20a doesn't contain any linux specific structs. 2) The common struct sim_gk20a contains an added function pointer which is used to invoke gk20a_sim_esc_readl() method. 3) sim_gk20a.c is moved to nvgpu/common/linux along with a new header sim_gk20a.h that contains the definition of struct sim_gk20a_linux. 4) struct gk20a now contains a pointer of sim_gk20a instead of the entire object. The memory for this struct is allocated and initialized during gk20a_init_support() and freed during invocation of gk20_remove_support(). 5) We first obtain the pointer for struct sim_gk20a_linux from the pointer of sim_gk20a using the container_of method in order to work on the struct.
