Add a kernel timer driver for the MEC1501 32KHz RTOS timer.
This timer is a count down 32-bit counter clocked at a fixed
32768 Hz. It features one-shot, auto-reload, and halt count down
while the Cortex-M is halted by JTAG/SWD. This driver is based
on the new Intel local APIC driver. The driver was tuned for
accuracy at small sleep values. Added a work-around for RTOS
timer restart issue. RTOS timer driver requires board ticks per
second to be 32768 if tickless operation is configured.

The previous code limited the length of a write to the size of a page,
but did not check whether the starting position was far enough into the
page that the write would still cross a page boundary.

This was always intended to be a bytestring rather than an array, but
full support was missing. Since that has been addressed switch it to

The driver historically used the erase block size (64 KiBy) as the page
size. There are other viable "sector" sizes, and for some applications
this one may be too large. Allow the application to specify the desired
flash page size.

The JEDEC API defines the hardware page, sector, and block sizes.
Deprecate the Kconfig settings, remove the `erase-size-block` property,
and add `has-be32k` to indicate that 32K-byte erase is supported.
Rework the driver to use the constants instead of configured values.

On some SoCs the frequency of the system clock is obtained at run time
as the exact configuration of the hardware is not known at compile time.
On such platforms using CONFIG_SYS_CLOCK_HW_CYCLES_PER_SEC define
directly introduces timing errors.
This commit replaces CONFIG_SYS_CLOCK_HW_CYCLES_PER_SEC by the call
to inline function sys_clock_hw_cycles_per_sec() which always returns
correct frequency of the system clock.

This patch introduces a dedicated work queue for handling the events
from ISR (i.e. for notifying the USB device stack, for executing the
enpoints callbacks, etc.). The system work queue cannot be used for
this purpose as it might be used in applications for scheduling USB
transfers and this could lead to a deadlock when the USB device stack
would not be notified about certain event because of a system work
queue item waiting for a USB transfer to be finished.
The FIFO named so far `work_queue` is renamed to `usbd_evt_fifo`
to better indicate its purpose and to avoid confusion.
