Subject: [PATCH 1/2] phy: qcom-qmp-usb: fix register offsets for ipq8074/ipq6018

Commit 2be22aae6b18 ("phy: qcom-qmp-usb: populate offsets configuration")
introduced register offsets to the driver but for ipq8074/ipq6018 they do
not match what was in the old style device tree. Example from old
ipq6018.dtsi:

<0x00078200 0x130>,     /* Tx */
<0x00078400 0x200>,     /* Rx */
<0x00078800 0x1f8>,     /* PCS */
<0x00078600 0x044>;     /* PCS misc */

which would translate to:
{.., .pcs = 0x800, .pcs_misc = 0x600, .tx = 0x200, .rx = 0x400 }

but was translated to:
{.., .pcs = 0x600, .tx = 0x200, .rx = 0x400 }

So split usb_offsets and fix USB initialization for IPQ8074 and IPQ6018.
Tested only on IPQ6018
