Subject: [PATCH v3 3/5] mtd: spinand: identfiy SPI NAND device with Continuous Read mode

From: Shivamurthy Shastri <sshivamurthy@...ron.com>

Add SPINAND_HAS_CR_FEAT_BIT flag to identify the SPI NAND device with
the Continuous Read mode.

Currently, some of the Micron SPI NAND devices enable this feature by
default, and we need to identify them to disable while probing.
