Adds ANDROID_OEM_DATA and ANDROID_OEM_DATA_ARRAY macros to add OEM-specific fields to kernel data structures to enable value-added features implemented in vendor modules. Fields defined with these macros must not be used by SoC vendors who must use the ANDROID_VENDOR_DATA* macros to add vendor fields.
