No need to ask, the PDF even mentions it:

"Qualcomm-Atheros QCA9880 Version 2, XB140 Reference Design"

XB140 is a dual band 3x3 board.

I was actually referring to the internal chip id, not PCI id, which is a
good way to check what chip it really is:

static int ath10k_core_check_chip_id(struct ath10k *ar)
	u32 hw_revision = MS(ar->chip_id, SOC_CHIP_ID_REV);

	ath10k_dbg(ATH10K_DBG_BOOT, "boot chip_id 0x%08x hw_revision 0x%x\n",
		   ar->chip_id, hw_revision);
