rockchip: rk3288-firefly: Drop use of silent console and late boardinfo

Current use of SILENT_CONSOLE hide valuable information when something
goes wrong during boot, drop this Kconfig option to allow user to see
e.g. from what media U-Boot proper is loaded from.

A second Model line is printed on console due to DISPLAY_BOARDINFO_LATE,
drop this Kconfig option to remove the second redundant line.
