The existing uart driver ns16550 did not have ISR locking that
effected IO APIC working in fixed delivery mode in SMP system
x86_64. This commit adds ISR locking mechanism using spinlock
for the interrupt related services.
The CONFIG_IPM_CONSOLE_STACK_SIZE is increased to lift
limitation of stack size experienced in IPM driver test with
this spinlock impelentation.

this case isn't designed for SMP, setting CONFIG_MP_NUM_CPUS=1 to
run the full SMP kernel config, but with only one CPU available.
Fixes: #12478.

This test was having trouble earlier (at least with some toolchains),
but whatever was causing that seems to have been fixed. The only
remaining issue is that neither the IPM console code nor the test are
SMP-safe. There's a bug (#14639) tracking the need to get these
working, but for now the straightforward workaround is just to disable
SMP.
And even long term, IPM is an oddball interprocessor communication
mechanism designed for asymmetric multiprocessing devices like Quark
SE and doesn't seem like an obvious fit for a SMP machine.

Disabled the CONFIG_COVERAGE for benchmarks and other tests.
This is needed because it interferes with normal behavior of the
test case.
