drivers/staging: make android lowmemorykiller.c explicitly non-modular
The Kconfig currently controlling compilation of this code is:
drivers/staging/android/Kconfig:config ANDROID_LOW_MEMORY_KILLER
drivers/staging/android/Kconfig: bool "Android Low Memory Killer"
...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 init.h and moduleparam.h ; the latter since
this file was previously implicitly relying on getting that header.
We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.
