559a8f1d3b lib: sbi: Simplify timer platform operations
Instead of having timer_value(), timer_event_start(), and
timer_event_stop() callbacks in platform operations, it will
be much simpler for timer driver to directly register these
operations as device to the sbi_timer implementation.

a63f05f3de lib: utils/timer: Initialize all matching timer DT nodes
We can have multiple matching DT nodes of the same FDT timer driver
so in this case we should call cold_init() for all matching DT nodes
instead of just first matching DT node.

The improved fdt_find_match() can be used to find multiple
match nodes.
