dt-bindings: mmc: sdhci-am654: Add flag to force setting of TESTCD bit
The ARASAN MMC controller on Keystone 3 class of devices needs the SDCD
line to be connected for proper functioning. Similar to the issue pointed
out in sdhci-of-arasan.c driver, commit 3794c542641f ("mmc:
sdhci-of-arasan: Set controller to test mode when no CD bit").
In cases where SDCD line is not connected, adding
"ti,fails-without-test-cd" in the DT node helps to indicate the
controller, that the SDCD line has been pulled down, using the TESTCD bit.
