ath9k: add a quirk to set use_msi automatically

Some platform(BIOS) blocks legacy interrupts (INTx), and only allows MSI
for WLAN device. So adding a quirk to list those machines and set
use_msi automatically.
Adding the following platforms to the quirk.
   Dell Inspiron 24-3460
   Dell Inspiron 3472
   Dell Inspiron 14-3473
   Dell Vostro 3262
   Dell Vostro 15-3572
