Subject: [PATCH] dmaengine: pl330: set subsys_initcall level

module_amba_driver is macro for module_init/exit
module_init is device_initcall level when it configured
with built-in driver.

pl330 is dmaengine driver. because slave drivers depend on
dmaengine drivers, dmaengine drivers is more appropriate
subsys_initcall.
