3502fbcc25 mtd: maps: add missing iounmap() in error path
This patch was triggered by the following Coccinelle error:

./drivers/mtd/maps/sc520cdp.c:246:3-9: \
	ERROR: missing iounmap; ioremap on line 242 \
	and execution via conditional on line 244

Since do_map_probe() is also invoked in this loop, it is also necessary to
map_destroy() any initialised struct mtd_info.

807c162533 mtd: spi-nor: fix spansion quad enable
With the S25FL127S nor flash part, each writing to the configuration
register takes hundreds of ms. During that  time, no more accesses to
the flash should be done (even reads).

This commit adds a wait loop after the register writing until the flash
finishes its work.

This issue could make rootfs mounting fail when the latter was done too
much closely to this quad enable bit setting step. And in this case, a
driver as UBIFS may try to recover the filesystem and may broke it
completely.
