dma/idxd: configure maximum batch size to high value
When configuring an Intel DSA instance using the utility script
dpdk_idxd_cfg.py, explicitly set the max supported batch size value to a
high value, to ensure large bursts are supported if so desired. The
default in the linux kernel is now just 32 [1], which may not be
sufficient for all DPDK apps.

dma/idxd: fix wrap-around in burst capacity calculation

dma/idxd: fix wrap-around in burst capacity calculation
The burst capacity calculation code assumes that the write and read
(i.e. ids_returned) values both wrap at the ring-size, but the read
value instead wraps as UINT16_MAX. Therefore, instead of just adding
ring-size to the write value in case the read is greater, we need to
just always mask the result to ensure a correct, in-range, value.

dma/idxd: fix paths to driver sysfs directory

dma/idxd: fix paths to driver sysfs directory
Recent kernel changes[1][2] mean that we cannot guarantee that the paths
in sysfs used for creating/binding a DSA or workqueue instance will be
as given in the utility script, since they are now "compatibility-mode
only". Update script to support both new paths and compatibility ones.
