drm/i915/ltphy: Nuke bogus weird timeouts

Browse source

The LT PHY code is abusing intel_de_wait_custom() in all kinds of weird
ways. Get rid of the weird fast timeouts, and just use the slow ones.
For consistency with intel_wait_for_register() we'll stick to the
default 2 usec fast timeout for all cases.

Someone really needs to properly document where all these magic numbers
came from...

This will let us eventually nuke intel_de_wait_custom() and convert
over to poll_timeout_us().

v2: Go for the longer (ms) timeout in case it actually matters
