Subject: [PATCH 02/10] drivers/pci: make host/pcie-spear13xx.c driver explicitly non-modular

The Kconfig for this option is currently:

config PCIE_SPEAR13XX
        bool "STMicroelectronics SPEAr PCIe controller"

...meaning that it currently is not being built as a module by anyone.
Lets remove the couple traces of modularity, 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.  An
alternate init level might be worth considering at a later date.

We explicitly disallow a driver unbind, since that doesn't have a
sensible use case anyway, and this driver had not populated ".remove"
with any function to be called either.

We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.
