apalis_t30: fix PCIe by forcing GEN1 speed
Enable PCI quirk support resp. don't explicitly disable it in order for
the following fix to take effect.
The Apalis evaluation board needs to set the link speed to 2.5 GT/s
(GEN1). The default link speed setting is 5 GT/s (GEN2). 0x98 is the
Link Control 2 PCIe Capability Register of the PEX8605 PCIe switch. The
switch supports link speed auto negotiation, but falsely sets the link
speed to 5 GT/s.
