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.

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.

We update timer drivers makefile to use kconfig for enabling/disabling
drivers. To avoid compile errors, we also enable appropriate timer
drivers for each platform.

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.

We add simple timer framework which will select and use timer driver
based on details in FDT passed by previous booting stage.
