fix: mtdparts: fix mtdparts command failure (invalid SPI identification)

	- fix 'mtdids' env. variable, replaced the delimiter ';' with ','
	- fix mtdparts parsing behavior:
	   Before, when a failure occurs in parsing the device the
	   whole parse process fails
	   After, it continues to parse the next device.
	- ignore the quotation marks in 'mtdparts' env. variable.
	- Fixed JIRA: SYSTEMSW-1092
