ubifs: introduce UBIFS_ATIME_SUPPORT to ubifs
To make ubifs support atime flexily, this commit introduces
a Kconfig option named as UBIFS_ATIME_SUPPORT.
With UBIFS_ATIME_SUPPORT=n:
ubifs keeps the full compatibility to no_atime from
the start of ubifs.
=================UBIFS_ATIME_SUPPORT=n=======================
-o - no atime
-o atime - no atime
-o noatime - no atime
-o relatime - no atime
-o strictatime - no atime
-o lazyatime - no atime
With UBIFS_ATIME_SUPPORT=y:
ubifs supports the atime same with other main stream
file systems.
=================UBIFS_ATIME_SUPPORT=y=======================
-o - default behavior (relatime currently)
-o atime - atime support
-o noatime - no atime support
-o relatime - relative atime support
-o strictatime - strict atime support
-o lazyatime - lazy atime support
