[U-Boot] [PATCH] pico-imx7: Disable video support

[Fabio Estevam]

Since commit 9e3c0174da842 ("pico-imx7d: Add LCD support") loading U-Boot
via USB download mode causes the following hang:

SDP: initialize...
SDP: handle requests...
Downloading file of size 527088 to 0x877fffc0... done
Jumping to header at 0x877fffc0
Header Tag is not an IMX image

U-Boot 2019.04-rc4-00047-gcfb3e102c4 (Mar 23 2019 - 10:45:10 -0300)

CPU:   Freescale i.MX7D rev1.2 1000 MHz (running at 792 MHz)
CPU:   Commercial temperature grade (0C to 95C) at 40C
Reset cause: POR
Board: i.MX7D PICOSOM
I2C:   ready
DRAM:  512 MiB

(Hangs here)

When booting from eMMC such hang does not happen and currently
we don't have a proper fix for this.  Also, this hang in USB
download mode only happens with the older version of the
board that has 512MB of memory.

As a temporary workaround, remove video support so that users
do not have a negative experience in case they brick their board
and want to recover from USB.

We can re-add video support later when a proper fix is in place.
