Erasing the whole flash takes approximately 7s on one of my test
machines. Expand the timeout accordingly.
Note however that it is in general not allowed to hold the flash
semaphore for so long and "firmware might implement a timeout
mechanism and take ownership of the relevant [lock]" after one second.
So a chip erase should better only be done when firmware doesn't make
use of the flash.
