qualcommax: ipq50xx: ax6000: enable pcie1 for QCA9887

Browse Source 
The Xiaomi AX6000 has three radios:
  - IPQ5018 integrated 2.4 GHz (ath11k AHB, wifi0)
  - QCN9024 on PCIe0 (ath11k PCI, QCA8074-class 5 GHz)
  - QCA9887 on PCIe1 (ath10k, 5 GHz)

The DTS previously kept pcie1 disabled because the controller
could not bring the link up. The real cause was the PERST GPIO
polarity: the stock device-tree uses GPIO_ACTIVE_HIGH on GPIO18
for the QCA9887 card, while OpenWrt had GPIO_ACTIVE_LOW, leaving
the card held in reset.

With the correct polarity the PCIe1 link trains and the QCA9887
enumerates at 01:00.0. ath10k loads firmware-2.bin, registers
phy0 with mac80211, and provides a functional 5 GHz AP.

Tested on a reworked Xiaomi AX6000 with QCA9887 soldered in.
All three radios enumerate, load firmware and beacon
successfully; scan, association and data traffic confirmed on
each radio.
