[PATCH v2 1/8] hw: Move i.MX watchdog driver to hw/watchdog

[Guenter Roeck]

In preparation for a full implementation, move i.MX watchdog driver
from hw/misc to hw/watchdog. While at it, add the watchdog files
to MAINTAINERS.

v2: Instead of auto-selecting WDT_IMX2 if IMX is enabled, select it 
    explicitly for each emulation using it.
    In Makefile, fix CONFIG_WDT_IMX -> CONFIG_WDT_IMX2
