dmaengine: ppc4xx: remove DRIVER_ATTR() usage

Browse source 
It's better to be explicit and use the DRIVER_ATTR_RW() and
DRIVER_ATTR_RO() macros when defining a driver's sysfs file.

Bonus is this fixes up a checkpatch.pl warning.

This is part of a series to drop DRIVER_ATTR() from the tree entirely.
