boards: arm: Add mcuboot flash partitions to mimxrt685_evk
Adds flash partitions and chosen nodes to the mimxrt685_evk device tree
to support mcuboot on the external octal SPI flash. This flash is rated
for 100K minimum program-erase cycles per sector, therefore this
partition configuration supports approximately 100K / (24576/8128) =
33073 upgrades.
Tested with samples/subsys/mgmt/mcumgr/smp_svr. The image swap takes
about a minute and a half to complete.
