Subject: [PATCH v3 00/11] PCI: imx6: Fix\rename\clean up and add lut
 information for imx95

Fixed 8mp EP mode problem.

imx6 actaully for all imx chips (imx6*, imx7*, imx8*, imx9*). To avoid     
confuse, rename all imx6_* to imx_*, IMX6_* to IMX_*. pci-imx6.c to        
pci-imx.c to avoid confuse.                                                

Using callback to reduce switch case for core reset and refclk.            

Add imx95 iommux and its stream id information.                            

Base on linux-pci/controller/imx
