soc/intel/common/block: Add max SPI transaction time-out as 5 sec 

Earlier 15ms time-out was kept for SPI transactions which was not
enough for SPI Erase transactions.

Increase the max time-out time to 5 secs which was present in SKL
before common code.
This increase in time-out won't disturb other SPI transactions like
Read, Write or Read Status, since, for those it will come out of
the loop once FDONE bit or FCERR bit is set.

BUG=b:63959637
BRANCH=none
TEST=Built and booted poppy and all SPI transactions succeeded.
