[PATCH v2] Bluetooth: btintel: Add devices to HCI_QUIRK_BROKEN_LE_CODED

[Werner Sembach]

From: Christoffer Sandberg <cs@tuxedo.de>

For HW variants 0x17, 0x18 and 0x19 LE Coded PHY causes scan and
connection issues when enabled. This patch disables it through
the existing quirk.

Perhaps the following could be a proper fix for that:

https://patchwork.kernel.org/project/bluetooth/patch/20240405204037.3451091-1-luiz.dentz@gmail.com/

If you manage to test it please reply and add Tested-by to its thread.

Sorry I never answered, but the problem seems to be gone with the current kernel version, don't know which patch fixed it exactly though.
