I've overridden get_cd of the driver, below is the patch:

I've refactored the code, setting FCD bit after sdhci_probe() with a separate
function to make the purpose more clear.

If the device attached to the MMC bus is not removable, set force card-detect
bit to bypass card detection procedure, so card detection pin can be used for
other purposes.
It's also a workaround for SAMA5D2 who doesn't drive CMD if using GPIO for card
detection.

"wdt" is a better name for watchdog rather than generic "priv".

SAM9X60 has a slightly different watchdog implementation:
- Timer value moved into a new register WLR
- Some MR register fields have their position changed
This patch add SAM9X60 support, also adds a compatible
for SAMA5D4 who is the same as existing SAM9260.

Use the name "mr" since we are referring to timer mode register.
