The Kconfig for this driver is currently:
config MV_XOR
bool "Marvell XOR 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.
Since module_init translates to device_initcall in the non-modular
case, the init ordering remains unchanged with this commit.
We leave some tags like MODULE_AUTHOR for documentation purposes.
Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.
