fix: sdio, fdt: enable SDIO Device Tree node for DB-381/2 board

	The default configuration for board is now with SPI0  & SDIO(4Bit)

	- enabled Boolean default entry indicating existance of SD/MMC unit
	  for DB-381/2 board
	- removed the disable option for this:
	  also if not detecting the 8Bit detected module, the default config will remain.

	this affects only on the Device Tree update logic.
	*JIRA SYSTEMSW #1658*
