From: Fu Wei <fu.wei@xxxxxxxxxx>
The patch introduce two new structs: arch_timer_mem, arch_timer_mem_frame.
And also introduce a new define: ARCH_TIMER_MEM_MAX_FRAMES
These will be used for refactoring the memory-mapped timer init code to
prepare for GTDT

Since struct is introduced but not used in this patch, how about
squash it with patch 12/17?
Thanks
