Qemu implements HPET so that it is connected to IRQ 2, which makes
necessary to use it in legacy emulation mode.
Add legacy emulation mode to HPET driver.
Change the way the HPET driver is initialized. QEMU requires that
the mode (one shot or periodic) gets set prior loading comparator
value.
Add debugging mode to HPET driver to ease the next port.

Flash size

This will allow them to be hoisted out of the platform's linker script file

This fixes issues building in a tree which has symlinks in its path,
for some reason PROJECT_BASE ends up having symlinks removed from it
but not ZEPHYR_BASE, causing Python to generate relative paths
with "../.." (for example) in the beginning. This patch ensures both
have symlinks removed before computing SOURCE_DIR.

Kbuild doesn't like absolute paths since it can't compute an outdir path
by applying a prefix. Convert to relative path before calling the kernel
Make session.
This will not work for projects that are completely outside the Zephyr
tree as leading ../ in the relative SOURCE_DIR will mess up the outdir
calculation.

The basic_atom uses the LOAPIC timer, which means that the proper value for
SYS_CLOCK_HW_CYCLES_PER_SEC is dependent upon the hardware. Although the
proper value for the atom_n28xx hardware is 150000000, that value does not
necessarily play well with QEMU and the host development platform as it has
been observed on many development boxes to result in a real tick frequency
that is too high.
It is recognized that the developer's host platform can not be controlled for
and that the new value of 900000000 will not be ideal for all systems. Pending
further feedback, it should be an improvement over the previous.

Fixes the SYS_CLOCK_HW_CYCLES_PER_SEC Kconfig option dependencies such that
it can be overridden by a modified platform configuration file. This is
particularly important for the LOAPIC timer driver as
SYS_CLOCK_HW_CYCLES_PER_SEC is dependent upon the target's CPU/bus frequency.
