Subject: [PATCH v2 0/2] mtd: rawnand: Add NAND controller support on Intel LGM SoC

This patch adds the new IP of Nand Flash Controller(NFC) support
on Intel's Lightning Mountain(LGM) SoC.

DMA is used for burst data transfer operation, also DMA HW supports
aligned 32bit memory address and aligned data access by default.
DMA burst of 8 supported. Data register used to support the read/write
operation from/to device.

NAND controller also supports in-built HW ECC engine. 

NAND controller driver implements ->exec_op() to replace legacy hooks,
these specific call-back method to execute NAND operations.

Thank you very much Boris, Martin and Andy for the suggestions and inputs.
---
v2:
  - implement the ->exec_op() to replaces the legacy hook-up.
  - update the commit message
  - YAML compatible string update to intel, lgm-nand-controller
  - add MIPS maintainers and xway_nand driver author in CC

v1:
 - initial version
