Aseda Aboagye 8f3f0c0807 flash_ec: Add 1s delay after turning on SPI VREF.
On zoombini, we were taking enough power that the voltage dipped for a
little bit.  This commit adds a 1 second delay after applying SPI VREF
but before actually flashing the EC.

BUG=b:65694390
BRANCH=None
TEST=`./util/flash_ec --board zoombini` still works.
