The name of mi_cmdline in acrn_boot_info structure would cause confusion with
mi_cmdline in multiboot_info structure, rename it to cmdline. At the same time,
the data type is changed from pointer to array to avoid accessing the original
multiboot info region which might be used by other software modules.

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.

Generalize and split basic cpu cycle/tick routines from x86/timer:

- Instead of get_tsc_khz(), use cpu_tickrate() in generic code.
- Include "common/ticks.h" instead of "x86/timer.h" in generic code.
- CYCLES_PER_MS is renamed to TICKS_PER_MS.
The x86 specific API rdstc() and get_tsc_khz(), as well as TSC_PER_MS

by static analysis tool.
According to naming convention rule: If the data
structure type is used by multi modules, its
corresponding logic resource is only used by
hypervisor/host and isn't exposed to external
components (such as SOS, UOS), its name meaning
is simplistic (such as timer), its name needs prefix
"hv_".
