Subject: [PATCH v11 3/3] EDAC: nuvoton: Add NPCM memory controller driver

From: Medad CChien <ctcchien@...oton.com>

Add memory controller support for Nuvoton NPCM SoC.

Note:
    you can force an ecc event by writing a string to edac sysfs node
    and remember to define CONFIG_EDAC_DEBUG to enable this feature
    example: force a correctable event on checkcode bit 0
    echo "CE checkcode 0" to below path
    /sys/devices/system/edac/mc/mc0/forced_ecc_error

Datasheet:
    Cadence DDR Controller Register Reference Manual For DDR4 Memories
    Chapter 2: Detailed Register Map
