[PATCH] mtd: spi-nor: issi: Add support for ISSI IS25LP512MG

[Matthew Parker]

Add support for the ISSI IS25LP512MG 512Mbit (64 MiB) SPI NOR flash.

The device provides JESD216B SFDP tables which accurately describe
fast-read modes and erase geometry. Flash read, write, and erase
operations across the full 64 MiB array have been verified on hardware.
