ascend inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I49RB2 CVE: NA
---------------------------------------------------
To support device tree boot for arm64 mpam, the __init macro might be used by the dts driver. This remove the necessary __init macro for the related functions.
