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.

For platforms not having TIME CSR, we trap-n-emulate TIME CSR
read/write in OpenSBI. Same rationale applies to HTIMEDELTA CSR
as well so we trap-n-emulate HTIMEDELTA CSR for platforms not
having TIME CSR.

The target_hart and hartid paramter of TIMER callbacks is not
required because it always current hartid which can be obtained
using sbi_current_hartid() API.

Instead of having separate timer_init() hooks for cold and
warm boot, this patch updates struct sbi_platform to have just
one timer_init() hook. The type of boot (cold or warm) is now
a boolean flag parameter for the updated timer_init() hook.
