Since U-Boot now supports EFI and FB passing via EFI GOP, when booting rockchip SoCs via EFI, a EFI FB is available. However, currently when re-initializing display pipeline, the EFI FB is not removed, lead to fbcon not working (because the EFI FB is no longer bound to the display pipeline although it's still /dev/fb0 and fbcon is bound to it). Add some code for removing firmware-based FB when initializing KMS of rockchipdrm. Tested on Pinebook Pro (RK3399) with U-Boot patchset for initializing eDP display applied.
