Subject: [PATCH] crypto: qat - remove global CSRs helpers
Git-commit: 8f87b6271ec85c09af6406665324c74bb79e3216
References: jsc#SLE-14454
Patch-mainline: v5.11-rc1
Include the offset of GLOBAL_CSR directly into the enum hal_global_csr
and remove the macros SET_GLB_CSR/GET_GLB_CSR to simplify the global CSR
access.
