Subject: [PATCH resend] selftests: timers: clocksource-switch: Adapt progress to kselftest framework
When adapting the test to the kselftest framework, a few printf() calls
indicating test progress were not updated.
Fix this by replacing these printf() calls by ksft_print_msg() calls.

When just running the test, the output looks like:
# Validating clocksource arch_sys_counter
TAP version 13
1..12
ok 1 CLOCK_REALTIME
...
# Validating clocksource ffca0000.timer
TAP version 13
1..12
ok 1 CLOCK_REALTIME
...
When redirecting the test output to a file, the progress prints are not
interspersed with the test output, but collated at the end:
TAP version 13
1..12
ok 1 CLOCK_REALTIME
...
TAP version 13
1..12
ok 1 CLOCK_REALTIME
...
# Totals: pass:6 fail:0 xfail:0 xpass:0 skip:6 error:0
# Validating clocksource arch_sys_counter
# Validating clocksource ffca0000.timer
...
This makes it hard to match the test results with the timer under test.
Is there a way to fix this? The test does use fork().
Thanks!
