If not, perhaps the clock driver should force the clock to be enabled (perhaps only if the DRM/KMS driver isn't enabled?).

As for the suggestion to simply never disable the plls / ahb gates by blocking them from ever being disabled in the sunxi clock driver, that is not really a solution either, as we want to be able to turn these things off to safe power on screen blank once control has been turned over to the kms driver.
Without wanting to take sides on the simplefb matter, can't you just use clk_ignore_unused in bootargs to work around the issue at hand? That's what I do on the Spring Chromebook.
