flash Kinetis: dynamic status detection before starting mass_erase

The change prevents starting mass_erase in unstable state of MCU
(RESET/WDOG loop).
mass_erase of secured MCU using manual reset button is supported.
Timeouts are measured by timeval_ms() instead of iteration count.
mass_erase timeout prolonged to 16 seconds because aborting
mass_erase in progress (deasserting reset) leaves the device
in security locked state.
