Update Atheros AR928X pcidev string

The AR9280 half Mini Card (HB92) supports 5GHz as confirmed by athn(4)'s
"The AR9220, AR9223 and AR9280 (codenamed Merlin) ..." paragraph.

pcidevs however wrongly identifies this device as
    athn0 at pci2 dev 0 function 0 "Atheros AR9281" rev 0x01: apic 2 int 17
    athn0: AR9280 rev 2 (2T2R), ROM rev 22, address 04:f0:21:30:37:de

athn(4) says AR9281 is 2GHz only, so the first line (pcidevs string) does
not match the real information on the second line (from real hardware).

Looking around, the PCI Vendor ID: 168c, Product ID: 002a are described as

* https://pcilookup.com/?ven=168c&dev=002a&action=submit
  "AR928X Wireless Network Adapter (PCI-Express)"
* https://pci-ids.ucw.cz/read/PC/168c/002a calls this
  "AR928X Wireless Network Adapter (PCI-Express)"
* https://github.com/torvalds/linux/blob/fc02cb2b37fe2cbf1d3334b9f0f0eab9431766c4/Documentation/devicetree/bindings/net/wireless/qca%2Cath9k.yaml#L27
says
        - pci168c,002a  # AR9280 and AR9283
* https://pcisig.com/membership/member-companies?combine=168c
  (empty, no result)
* NetBSD pcidevs is like ours
  product ATHEROS AR9281              0x002a AR9281

Im summary, "AR928X" seems more appropiate and matches both AR9280 and
AR9281 chipsets, so use that to avoid contradicting dmesg lines:
    athn0 at pci2 dev 0 function 0 "Atheros AR928X" rev 0x01: apic 2 int 17
    athn0: AR9280 rev 2 (2T2R), ROM rev 22, address 04:f0:21:30:37:de

stsp confirms how "Atheros naming is very convoluted."
