iwlwifi: pcie: move power gating workaround earlier in the flow

commit 0df36b90c47d93295b7e393da2d961b2f3b6cde4 upstream.

We need to reset the NIC after setting the bits to enable power
gating and that cannot be done too late in the flow otherwise it
cleans other registers and things that were already configured,
causing initialization to fail.

In order to fix this, move the function to the common code in trans.c
so it can be called directly from there at an earlier point, just
after the reset we already do during initialization.
