Fixes to allow FRAMEBUFFER_CONSOLE and phjanderson's Vsync fix

Both fixes dis/en-abled as per Kconfig options

Warning: FB console fix may be intefering with Vsync fix (100% cpu usage on 1 core due to a rkfbvsync thread on Linux)

FB console notes:
Problem arises because RK moved the screen turning on to lcdc removing
it from rk_fb, and then the framebuffer_console fails (producing a stick
reboot) for not finding the screen.

Recommended to set CONFIG_FRAMEBUFFER_CONSOLE and unset CONFIG_LOGO or
else only half the screen is available for the boot log
