i40e/base: increase PF reset max loop limit

With latest LANconf and NVMupdate tools, pf_reset failed due to Firmware not
being ready, so this patch increases I40E_PF_RESET_WAIT_COUNT to 200, using
original value defined for A0 silicon, in order to make sure that FW is ready.

Test result indicates that firmware became ready at the loop count of 114.
