iwlwifi: add shared clock PHY config flag for some devices
Some devices use a shared clock which is very sensitive to variations
and cause trouble in some situations. We need to set a bit in the phy
configuration to indicate that to the FW. To make this generic, add a
extra_phy_config_flags element to the device configuration and OR it
into the phy_cfg before sending it to the firmware. And also create a
set of configurations for devices that use shared clocks and need this
extra bit to be set.
