apm821xx: MBL: make mtd chip work

Browse Source 
The MBL has a 512KiB Microchip SST39VF040 chip for uboot and
not much else.

Thanks to Ewald who figured out that the "jedec-probe" vs.
"jedec-flash" was the wrong binding. With this information
and the jedec-probe support enabled => the chip works.

| Found: SST 39LF040
| 4fff80000.nor_flash: Found 1 x8 devices at 0x0 in 8-bit bank
