Use openocd auto-erase when writing flash, and use sysresetreq to reset
According to its datasheet, LM4 doesn't support vectreset, but does
support sysresetreq. Using sysresetreq properly resets all
peripherals and cleanly resets the LM4.
Auto-erase makes the flash command faster.
BUG=none
TEST=flash_link_ro, flash_link_a, flash_link, all with different images
