When the 'keep-config' property is populated, the
->setup_data_interface() hook of the driver is not shown to the core,
which leads to not "updating" the timings like tPROG_max.

While it worked with the old driver that hardcoded this delay, this
might not work anymore with the current driver because it expects
timings.sdr.tPROG_max to be != 0 (and PSEC_TO_MSEC(0) also returns 0).

This is probably something to fix.
