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. Change-Id: I8a14c6af45ea14d8e7f1ef38a589158f38d0c0ea Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
