[PATCH 0/2] Change behaviour of CONFIG_TIMER_EARLY

When CONFIG_TIMER_EARLY is selected and the timer driver implements
timer_early_get_count() and timer_early_get_rate() this leads to
an EAGAIN error one some configurations in...

common/board_f.c:initf_dm()

initf_dm() invokes dm_timer_init(), but this function returns with
an EAGAIN error in, because the DM virtual root driver isn't
initialized yet in...

drivers/timer/timer-class.c:dm_timer_init()

Moved error handling to...

lib/time.c

For details you can read the description in the patches.

Affected drivers:
drivers/timer/andes_plmt_timer.c
drivers/timer/sifive_clint_timer.c
drivers/timer/riscv_timer.c

I don't know who maintains these base libraries and base
functions, so I used the copyright holders. For the driver
I added the required maintainers to CC.
