[PATCH v2] imx8mq_evk: switch board to use binman for images

Currently i.MX8MQ EVK board still targeting the old image generation
approach for image generation, which relies on the FIT generator that
has been dropped from the tree.
Switch the board to use binman instead, which is a standard image
generator now.
Update board documentation to correct build command, and advise latest
firmware and TF-A versions to use.
NOTE: New image produced by binman does not have Signed HDMI FW support,
this has been left on the side and does not interfere with the general
boot flow.
Tested on: [i.MX8MQ rev2.0]

Changes in V2:
- Modify binman and documentation to use single flash.bin file instead
of flash.bin+u-boot.itb combination, suggested by Fabio Estevam.
