Move x86 architecture dependent per cpu data into a
seperate structure and embeded it in per_cpu_region.
caller could access architecture dependent member by
using prefix 'arch.'.
v2->v3:
move whose_iwkey, profiling_info and tsc_suspend to x86
v1->v2:
rebased on latest repo

This patch implements risc-v specific timer codes. Basically,
risc-v adapts to acrn timer framework with some specific
behaviors. So far, it enables sstc support in h-mode.

For arch specific codes, we use arch_xxx() to name the function.
So, rename cpu_ticks/cpu_tickrate/set_hw_timeout/init_hw_timer
to follow this convention. Then, use arch interface to set timeout
value in update_physical_timer().
Furthermore, remove hw_timer.h and move its contents into common/
timer.h.

Modified the copyright year range in code, and corrected "int32_tel"
into "Intel" in two "hypervisor/include/debug/profiling.h" and
"hypervisor/include/debug/profiling_internal.h".

Many of the license and Intel copyright headers include the "All rights
reserved" string. It is not relevant in the context of the BSD-3-Clause
license that the code is released under. This patch removes those strings
throughout the code (hypervisor, devicemodel and misc).

1. do not allow external modules to touch internal field of a timer.
2. make timer mode internal, period_in_ticks will decide the mode.
API wise:
1. the "mode" parameter was taken out of initialize_timer().
2. a new function update_timer() was added to update the timeout and
period fields.
3. the timer_expired() function was extended with an output parameter
to return the remaining cycles before expiration.
Also, the "fire_tsc" field name of hv_timer was renamed to "timeout".
With the new API, however, this change should not concern user code.

x86/timer.[ch] was moved to the common directory largely unchanged.
x86 specific code now resides in x86/tsc_deadline_timer.c and its
interface was defined in hw/hw_timer.h. The interface defines two
functions: init_hw_timer() and set_hw_timeout() that provides HW
specific initialization and timer interrupt source.
Other than these two functions, the timer module is largely arch
agnostic.
