post_boot: modify hispeed_freq for 8974 pro

The interactive governor is configured with a hispeed
frequency of 1.5 GHz. This causes L2 to be bumped up to
1.5 GHz as well, which requires a turbo CX voltage and
affects power. To save power when the hispeed frequency
is triggered, change the hispeed frequency to 1.2 GHz,
which has the highest L2 frequency that can be supported
by a nominal CX voltage.
