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 (is already applied) 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().

- Applied R-b tags [Fabio Estevam], [Oleksandr Suvorov].
- Rebased on the latest u-boot-imx/master.
- Excluded from patch series c115cd154c("pinctrl: nxp:
DM_FLAG_PRE_RELOC by default") as it was already applied by Stefano
- Addressed comments [Fabio Estevam].
