ipq806x: Fix wireless support for Netgear Nighthawk X4S D7800

D7800 has a simular hardware to R7800 and uses dual QCA9980 for both 2.4GHz and 5GHz band.
However there is no proper initialization for them, which causes a kernel panic due to failed firmware loading.

This patch adds d7800 to ath10k caldata extraction list.
I can get two functional wireless bands after making change to it.
