Some small fixes for arch_timer_edge_cases that I stumbled upon while debugging failures for this selftest on ampere-one.
I’ve tested this test under three circumstances:
1) Original (!HAS_EL2 && !HAS_EL2_E2H0)
2) HAS_EL2 && HAS_EL2_E2H0
3) HAS_EL2 && !HAS_EL2_E2H0
Tests 1) and 2) returned in approx. the same amount of real time (about 12s) although 3) doesn’t seem to return at all.
I’ve tested it on ampere-one.

Changes since v1:
- determine effective counter width based on suggestions from Marc
Changes since v2:
- new patch to fix xval initialization
I've done tests with this on various machines - no issues during several hundreds of test runs.
