The Kconfig currently controlling compilation of these files is:
config SH_DMAE_BASE
bool "Renesas SuperH DMA Engine 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.
In one file, we explicitly disallow a driver unbind, since that
doesn't have a sensible use case anyway, and there was not a
".remove" code assigned in the struct for it either.
Since module_init translates to device_initcall in the non-modular
case, the init ordering remains unchanged with this commit.
Similarly builtin_platform_driver and module_platform_driver use
device_initcall, so the init ordering remains unchanged there too.
In one file, We replace module.h with moduleparam.h since the file does
have one module_param already.
We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.
