i2c: designware: Fix bogus sda_hold_time due to uninitialized vars

We need to initializes those variables to 0 for platforms that do not
provide ACPI parameters. Otherwise, we set sda_hold_time to random
values, breaking e.g. Galileo and IOT2000 boards.

Fixes: 9d6408433019 ("i2c: designware: don't infer timings described by ACPI from clock rate")
