fix: mtdburn: msys: disable 'entire NAND erase' when using SPI

	Before, when using 'mtdburn' command with 'spi' flag
	it showed:
	 "Going to erase the entire NAND flash.
	  Do you want to continue ? [Y/n]"
	which is irrelevant for spi.

	- Removed this step when burning to spi
	- Fixed JIRA:SYSTEMSW-1725
