The Kconfig currently controlling compilation of this code is:
config ACPI_APEI_GHES
bool "APEI Generic Hardware Error Source"
...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 replace module.h with moduleparam.h as we are keeping the
pre-existing module_param that the file has, as currently that is
the easiest way to maintain compatibility with the existing boot
arg use cases.
