stm32f1x: Increase options erase timeout

The erase time for the option byte page is not directly specified but is
assumed to be the same as the other pages (or mass erase) which is 20 to
40 ms. The current timeout value is 10 which means 10 ms plus the time to
poll the status flag that many times.

With faster interfaces or drivers (such as when using the ftdi driver
instead of the ft2232 driver) the adapter delay is not enough in some
cases, unless the jtag freq is reduced as a workaround. The result is a
"timed out waiting for flash" error when trying to write the options.

Increase the timeout to a minimum of 100 ms, which is in line with the
other erase timeouts. Also make defines of both the erase and the program
timeouts.
