For Colibri iMX6ULL we have to set pinmux for uart configuration ASAP
(ideally before relocation) to get serial console working. Without this
we miss almost the half of output (U-boot version, CPU defails,
Reset cause, DRAM details etc.).
To achieve this we need to force pinctrl-mx6 to get probed before
relocation and add u-boot,dm-pre-reloc properties to uart pinmux
configuration nodes. Setting pinmux configuration for UART before was done
in board_early_init_f().

pinctrl: nxp: mx6: DM_FLAG_PRE_RELOC by default
ARM: dts: imx6ull-colibri: pre-reloc for uart pinmux modes
