tests/fbcon_fbt: Add and user psr_long_wait_update()

When fbcon is enabled, PSR will be active between cursor blinks so
what it should really use to test PSR is psr_wait_entry(), so a new
feature callback was added.

But the fbcon cursor blinks at 5hz what give us 200ms between each
screen update what make psr_wait_update() prone to fail the test
because it timed out before a blink could happen, so here adding and
using psr_long_wait_update() that have a longer timeout.

v3:
- 3 previous patches squashed in this one (Maarten)
- Back to !feature->wait_until_enabled() to test feature state when
all CRTCS are disabled(Dhinakaran)
