--- Comment #1 from Stefan Roesch <shr@devkernel.io> ---
I think the problem is that you configured the efi framebuffer:

EFI framebuffer information:
addr, size     0xfe000000, 0x0
dimensions     0 x 0
stride         0
masks          0x00ff0000, 0x0000ff00, 0x000000ff, 0xff000000
clk u0_mipitx_dphy_clk_txesc already disabled

This needs to be disabled.
