[PATCH 00/10] bootstage: Migrate from timer_get_boot_us() to timer_get_us()

While working on the bootstage support for Armada XP (orion-timer)
I noticed, that we currently have two API's supporting early timer
functionality. These are:
a) timer_early_get_rate() & timer_early_get_count() which integrates
into the "normal" timer functions like timer_get() & timer_get_us()
in the early boot phase, if CONFIG_TIMER_EARLY is enabled
b) timer_get_boot_us(), which was introduced with bootstage IIUTC
IMHO it makes more sense to not introduce a new API for this early
timer functionality but re-use the "normal" API instead. This patchset
migrates the timer_get_boot_us() implementations to the timer_early
functions. This is done by:
- Implementing the timer_early functions in the drivers currently
supporting timer_get_boot_us()
- Migrating bootcount to using timer_get_us() instead of
timer_get_boot_us()
- Completely removing timer_get_boot_us()
With some minor tweaks in board_r/f for the dm_timer_init() and
timer_init() call.
I've tested this on Armada XP and sandbox.
Thanks,
Stefan
