[U-Boot] [PATCH v2 2/2] imx8: output SECO-FW and ATF commit IDs

[Anatolij Gustschin]

Borrow ID reading code from Ye Li (NXP U-Boot, commit ID 5b443e3e2617)
but drop imx-mkimage commit ID reading since we now use in tree mkimage.

Changes in v2:
 - reword subject and commit description
 - use in tree sc_seco_build_info() instead of adding
   sc_misc_seco_build_info()
 - drop output of imx-mkimage commit ID code
 - drop setting the IDs to environment because build_info()
   is called before environment init and setting variables
   doesn't work yet
