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 commit 4be26f695ffa ("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: 4be26f695ffa ("phy: qcom-qmp-pcie: fix memleak on probe deferral")
