[PATCH 4/8] PCI: portdrv: make it explicitly non-modular

[Paul Gortmaker]

The Makefile/Kconfig currently controlling compilation of this code is:

pcieportdrv-y               := portdrv_core.o portdrv_pci.o portdrv_bus.o
obj-$(CONFIG_PCIEPORTBUS)   += pcieportdrv.o

drivers/pci/pcie/Kconfig:config PCIEPORTBUS
drivers/pci/pcie/Kconfig:       bool "PCI Express Port Bus support"

...meaning that it currently is not being built as a module by anyone.

Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.

Since module_init translates to device_initcall in the non-modular
case, the init ordering remains unchanged with this commit.

We don't replace module.h with init.h since the file already has that.

Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

We also delete the MODULE_LICENSE tag etc. since all that information
is already contained earlier up in the file.
