mtd: spi-nor: support GigaDevice gd25lq64c (2016-05-10 15:44:18 -0700)

----------------------------------------------------------------
MTD updates for v4.7:

First cycle with Boris as NAND maintainer! Many (most) bullets stolen from him.

Generic:

* Migrated NAND LED trigger to be a generic MTD trigger

NAND:

* Introduction of the "ECC algorithm" concept, to avoid overloading the ECC
mode field too much more
* Replaced the nand_ecclayout infrastructure with something a little more
flexible (finally!) and future proof
* Rework of the OMAP GPMC and NAND drivers; the TI folks pulled some of
this into their own tree as well
* Prepare the sunxi NAND driver to receive DMA support
* Handle bitflips in erased pages on GPMI revisions that do not support
this in hardware.

SPI NOR:

* Start using the spi_flash_read() API for SPI drivers that support it (i.e.,
SPI drivers with special memory-mapped flash modes)

And other small scattered improvments.

----------------------------------------------------------------
