intel: Increase IDC timeout for FPGAs

Blocking IDC is used to call comp_free() for a DP component instantiated
on a different core than its pipeline. On FPGA, unloading an LLEXT module
takes almost 10 ms (for the SRC module, which has a lot of rodata).
In addition, log_flush() takes at least 5 ms if there are some logs
to flush. However, FPGA seems to have a tendency to have more deferred
logs, and log_flush() could take even more time. Let's increase the IDC
timeout for FPGA to 50 ms, compared to 15 ms on silicon.
