[U-Boot] [PATCH 11/16] armv7: timer: init timer with bootstage

[Patrick Delaunay]

In initf_bootstage() we call bootstage_mark_name() which ends up calling
timer_get_us() before timer_init(); that cause crash for stm32mp1.

This patch solve the issue without changing the initialization sequence.
See also commit 97d20f69f53e ("Enable CONFIG_TIMER_EARLY with bootstage")
for other solution when DM is activated for TIMER.
