bootstage_mark_name calls timer_get_boot_us which inturn calls
the arch timer. The arch timer uses the gd pointer to save the
lastinc count. A call to bootstage_mark_name here results in a
data abort as gd is uninitialized.

Though it is true that there are currently no users for this
feature, it isn't good to see an abort when someone tries to
use BOOTSTAGE. I was bugged by this error when trying to
use this feature on i.Mx6Q based board.
