phy: qcom-qmp-pcie: fix resource mapping for SDM845 QHP PHY
On SDM845 one of PCIe PHYs (the QHP one) has the same region for TX and RX registers. Since the commit4be26f695f
("phy: qcom-qmp-pcie: fix memleak on probe deferral") added checking that resources are not allocated beforehand, this PHY can not be probed anymore. Fix this by skipping the map of ->rx resource on the QHP PHY and assign it manually. Fixes:4be26f695f
