* [U-Boot] [PATCH] MTD: nand: mxs_nand_spl: Fix empty function pointer for BBT

The initialization function calls a nand_chip.scan_bbt(mtd) but
scan_bbt is never initialized resulting in an undefined function
pointer.  This will direct the function pointer to nand_default_bbt
defined in the same file.

Applied to u-boot-imx, master, thanks !

Fixes crashing NAND SPL loader on my i.MX6ULL board, which was
introduced in commit 5346c31e305a37d39f535cc0d5ae87d8b7e81230 and is
present in U-Boot since version 2018.07.

Tested on a custom i.MX6ULL board with a Micron NAND flash.
