drivers/dma: make mv_xor.c driver explicitly non-modular
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.
