mx6sabreauto: set SYS_MALLOC_F for video

Sabre Auto boards currently hang with:
```
U-Boot 2019.07-rc3-00057-gc41940c406 (Jun 03 2019 - 14:42:41 +0200)

CPU:   Freescale i.MX6QP rev1.0 996 MHz (running at 792 MHz)

Board: MX6Q-Sabreauto revA
I2C:   ready
DRAM:  2 GiB

```

Set SYS_MALLOC_F_LEN to reserve_video to work.

This is similar to the change Peng Fan did for mx6sabresd (9002e735e717)
