that u-boot setup framebuffers passed to the kernel (for early console

Perhaps this has been discussed earlier, but I started to wonder if
managing clocks is enough.
What about regulators (to power the LCD), gpios (to keep the LCD
enabled) and pinctrl (for video signals)? I guess any those could be
reset by the kernel if no driver uses them.
