Subject: [PATCH 1/2] usb: dwc3: pci: Update the macro names for USB PCIe device ID's for Alder Lake platforms

From: Shruthi Sanil <shruthi.sanil@...el.com>

The device ID 0x465e is defined for the USB3 device controller in the CPU
sub-system of Alder Lake N platform. Hence updating the macro name
accordingly.

The device ID 0x54ee is defined for the USB2 controller on the PCH
sub-system for Alder Lake N platform. Hence updating the macro name
accordingly.

The device ID's defined for Alder Lake P is shared between
Alder Lake P, Alder Lake PS and Alder Lake M.
Hence updating the macro name to ADL from ADLP to make it common
and keeping it aligned with the xHCI ID's naming convention.

As we have two device controllers on Alder Lake platforms
i.e. one on PCH sub-system and another on CPU sub-system(USB3),
appending _PCH for the USB2 device ID macro to differentiate
between the 2 ID's.
