stable inclusion from stable-v5.10.94 commit c2bd7c31de1a5f3bb5f9a30327c58501d08e2ad0 bugzilla: https://gitee.com/openeuler/kernel/issues/I531X9
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit eb03f2d2f6a4da25d286613717d10add9ce9f175 ]
Since the function has been simplified and only call iommu_init_ga_log(), remove the function and replace with iommu_init_ga_log() instead.
