mtd: rawnand: pl353: Add support for the ARM PL353 SMC NAND controller

Browse Source 
This hardware controller is embedded in XilinX Zynq-7000 SoCs and has
partial support for Hamming ECC correction.

This work is inspired from the original contributions of Punnaiah
Choudary Kalluri and Naga Sureshkumar Relli.
