Bjorn Helgaas a93b506e26 PCI: pciehp: Handle surprise add even if surprise removal isn't supported 
The PCIe spec (r3.0, sec 7.8.9) says Hot-Plug Surprise indicates support
for surprise *removal*, but pciehp checked this to determine if it should
handle presence detect interrupts for device *addition*.

Allow surprise device addition even if the slot doesn't advertise support
for surprise removal.

Keith has a platform with slots for front-loading SFF devices.  The slots
do not have attention buttons and do not support surprise removal, but they
do have presence detect.  In that case, we still want to use presence
detect for device addition.

Keith's original patch handled surprise insertions only if Hot-Plug Capable
is set.  I think that test is superfluous because pciehp only claims slots
that advertise Hot-Plug Capable (see get_port_device_capability()).
