These two timers were sharing pretty much the same code. Actually
mtl timer was a "superset" of cavs timer. Just merge them into a
single one called intel audio dsp timer (intel_adsp_timer).

General refactoring to clean up and futureproof this driver.
Remove false dependency on CONFIG_CAVS_ICTL. This requires the CAVS
interrupt mask API, but doesn't touch the interrupt controller driver.
Remove a racy check for simultaneous interrupts. This seems to have
been well intentioned, but it's needless: the spinlock around the
last_count computation guarantees that colliding interrupts will
correctly compute elapsed ticks (i.e. the last will compute and
announce zero ticks, which is correct and expected). And this opened
a tiny window where you could incorrectly ignore a just-set timeout.
Factor out the specific registers used (there are only five) into
pointer-valued macros instead of banging them directly.
Unify interrupt initialization for main and auxiliary cores.

Split Kconfig into individual files for each driver. This improves
overall readability of the Kconfig options.
