a387a8dff0 lib: utils/timer: Use fdt_driver for initialization
The timer driver subsystem does not need any extra data, so it can use
`struct fdt_driver` directly. The generic fdt_timer_init() performs a
best-effort initialization of all matching DT nodes.

99b01ab610 platform: Drop timer warm init and exit hooks
Now that driver lifecycle is managed from within the SBI timer core,
platforms need only to initialize the driver once during cold init.
Remove the remaining platform hooks that are no longer used.

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.
