um: Support SPARSE_IRQ
Motivation: IRQ KUnit tests are going to require CONFIG_SPARSE_IRQ [1] in
order to:
(a) reliably allocate additional (fake) IRQs and
(b) ensure we can test managed affinity, which is only supported with
SPARSE_IRQ.
It seems that the only thing necessary for ARCH=um is to tell the genirq
core to skip over our preallocated NR_IRQS.
Tested with:
$ ./tools/testing/kunit/kunit.py run
[...]
[13:55:58] Testing complete. Ran 676 tests: passed: 646, skipped: 30
[...]
This compares with pre-patch results:
Ran 672 tests: passed: 644, skipped: 28
i.e., we no longer skip tests that 'depend on SPARSE_IRQ', and existing
tests all pass.
