[RESEND] Bluetooth: Enable all supported LE PHY by default

[RESEND] Bluetooth: Enable all supported LE PHY by default

[Luiz Augusto von Dentz]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

This enables 2M and Coded PHY by default if they are marked as supported
in the LE features bits.
