Subject: [PATCH 5/8] PCI: spear13xx: make it explicitly non-modular

The Kconfig currently controlling compilation of this code is:

drivers/pci/host/Kconfig:config PCIE_SPEAR13XX
drivers/pci/host/Kconfig:       bool "STMicroelectronics SPEAr PCIe controller"

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

Lets remove the couple instances of modular code usage, 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.

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 at the top of the file in the comments.
