Move chip specific code to chip specific folder. This will allow multiple chip support in the future. Create new specific functions - Initialize hwpm structures - Reserve and release PMA and RTR apertures - Zero, update and check allowlists - Set and get fake registers for MC aperture on simulation - perfmon dt aperture enums Jira THWPM-41 Change-Id: Ib80f324283c8d29b5c6f7bb6345a6df2410954e6 Signed-off-by: Vedashree Vidwans <vvidwans@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/c/linux-nvidia/+/2620234 Reviewed-by: svc_kernel_abi <svc_kernel_abi@nvidia.com> Reviewed-by: Seema Khowala <seemaj@nvidia.com> Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com> GVS: Gerrit_Virtual_Submit
