[PATCH 6.0 0766/1073] phy: qcom-qmp-pcie: fix ipq8074-gen3 initialisation

From: Johan Hovold <johan+linaro@kernel.org>

[ Upstream commit 94b7288eadf6e2c09e6280c65a9d07cca01bf434 ]

The phy_status mask was never set for IPQ8074 (gen3) which meant that
the driver would not wait for the PHY to be initialised during power-on
and would never detect PHY initialisation timeouts.
