[PATCH v2 3/8] timer: orion-timer: Add timer_get_boot_us() for BOOTSTAGE support

[Stefan Roese]

Add timer_get_boot_us() to support boards, that have CONFIG_BOOTSTAGE
enabled, like pogo_v4.

Signed-off-by: Stefan Roese <sr at denx.de>

v2:
- Change timer_get_boot_us() to use the timer_early functions
- Remove #if CONFIG_IS_ENABLED(BOOTSTAGE)

Simon, I'm currently looking into this timer_get_boot_us() to using
timer_early_get_count() etc consolidation.
