Trim default ICH SPI delay from 1000 to 10 microseconds

Since many commands take around 10 microseconds to complete, it is
totally pointless to wait for 1000 microseconds before checking the
status again.

This patch is tested and reduced write time on ICH7 with SST25VF080B
from over one hour to 62 seconds.

Thanks to Ali Nadalizadeh for testing!

Corresponding to flashrom svn r487.
