arm: Move bootstage record for board_init_f() to after arch_cpu_init()
The timer may be inited in arch_cpu_init() so it is not safe to make a
bootstage mark before this is called. Arrange the code to fix this.
Note: The question was raised as to why we don't keep all archs in sync.
PowerPC doesn't have specific bootstage markers at present (although it
does use boot progress). I hope that the generic board series will solve
this problem in general, but in the meantime this is a real problem, and
only in ARM.
We now get a correct time for board_init_f:
Timer summary in microseconds:
Mark Elapsed Stage
0 0 reset
100,000 100,000 spl_start
848,530 748,530 board_init_f
907,301 58,771 board_init_r
910,478 3,177 board_init
