[PATCH] PCI/ACPI: make array pcie_to_hpx3_type static const, makes object smaller

[Colin King <colin.king@xxxxxxxxxxxxx>]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

Don't populate the array pcie_to_hpx3_type on the stack but instead
make it static const. Makes the object code smaller by 6 bytes:

Before:
   text	   data	    bss	    dec	    hex	filename
  19247	   3048	     64	  22359	   5757	drivers/pci/pci-acpi.o

After:
   text	   data	    bss	    dec	    hex	filename
  19177	   3112	     64	  22353	   5751	drivers/pci/pci-acpi.o

(gcc version 9.2.1, amd64)
