mtd: nand: Fix writing mtdoops to nand flash.
commit 30863e38ebeb500a31cecee8096fb5002677dd9b upstream.
When mtdoops calls mtd_panic_write(), it eventually calls
panic_nand_write() in nand_base.c. In order to properly wait for the
nand chip to be ready in panic_nand_wait(), the chip must first be
selected.
When using the atmel nand flash controller, a panic would occur due to
a NULL pointer exception.
Fixes: 2af7c6539931 ("mtd: Add panic_write for NAND flashes")
