fix Kinetis 100 MHz rev 1.x programming
Kinetis 100 MHz rev 1.x devices have no SMC and hence need different checking of the run mode. Details about the differences between rev 1.x and 2.x of the Kinetis 100 MHz series can be found here: https://www.nxp.com.cn/docs/en/application-note/AN4445.pdf Signed-off-by: Martin Hierholzer <martin.hierholzer@desy.de> Change-Id: Ib705385a931275159bdae9b31caecc6ec9c0da1e Reviewed-on: https://review.openocd.org/c/openocd/+/7015 Tested-by: jenkins Reviewed-by: Tomas Vanek <vanekt@fbl.cz>
