phy: qcom-qmp-pcie-msm8996: fix memleak on probe deferral

Browse source 
Switch to using the device-managed of_iomap helper to avoid leaking
memory on probe deferral and driver unbind.

Note that this helper checks for already reserved regions and may fail
if there are multiple devices claiming the same memory.

Fixes: e78f3d15e1 ("phy: qcom-qmp: new qmp phy driver for qcom-chipsets")
