Revert adv7511 mode whitelisting hack

This patch reversts the two following changes:

Commit dc0c1bea13e8 ("HACK: adv7511: Add support for 1024x600
resolution with clock = 50250").

And Commit cb930582f7aff ("HACK: adv7511: Re-add mode limiting
(this needs to go into drm driver)")

As we're pushing the mode whitelist hack into the kirin960
driver (the hikey kirin driver already has proper non-whitelist
mode validation calculations).
