iwlwifi: add trans_cfg for devices with long latency
A couple of SoCs, which can be recognized by PCI device IDs 0xA0F0 and
0x43F0, need a longer wait for the xtal to stabilize. To handle this,
add a new trans_cfg structure for Qu devices with a larger
xtal_latency value and apply them to the devices recognized by these
IDs. Also add a flag that allows us to inform the FW that the low
latency xtal should be used.
