MIPS: lantiq: Remove unused function pointer variables

Ever since introduction in the commit e47d488 ("MIPS: Lantiq: Add
PCI controller support.") ltqpci_plat_dev_init has been unused. In
57c8cb8 ("MIPS: pci: convert lantiq driver to OF") also
ltq_pci_plat_arch_init was introduced.

With those commit being more than 10 years ago, it seem neither is
going to get used anytime soon. Thus, remove both unused function
pointer variables.
