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.

If it is just these 3 then we are missing a break here.

The cases are not added by the patch, the fallthrough was here before. This patch just adds this quirk for these 3 cases on top to the other things done below, aka the fallthrough is intentional.

Best regards,
