[PATCH 3/3] mtd: rawnand: denali: Do not reset the block before booting the kernel

[Marek Vasut]

The Denali NAND block loses configuration when put in reset.
Specifically, RB_PIN_ENABLED, CHIP_ENABLE_DONT_CARE,
SPARE_AREA_SKIP_BYTES and SPARE_AREA_MARKER are lost.
Since mainline Linux depends on the configuration programmed
into the Denali NAND controller by the bootloader, do not
reset the controller before starting the kernel, otherwise
the kernel will read bogus values and fail to use the NAND.
