mtd: fsl-quadspi: Distinguish the mtd device names
Currently on a imx6sx-sdb board, which has two SPI NOR chips connected
to QSPI2 the following output from /proc/mtd is seen:
dev: size erasesize name
mtd0: 01000000 00010000 "21e4000.qspi"
mtd1: 01000000 00010000 "21e4000.qspi"
Attempts to partition them on the kernel command line result in both
chips with identical (and identically named) partitions, which is
an inconvenient behavior.
Assign a different mtd->name for each mtd device to avoid this problem.
After this change the output from /proc/mtd becomes:
dev: size erasesize name
mtd0: 01000000 00010000 "21e4000.qspi-0"
mtd1: 01000000 00010000 "21e4000.qspi-1"
In order to keep mtdparts compatibility keep the mtd->name
unchanged when a single SPI NOR is present.
