Arbitrate the IBs on nodes marked as dual config. This will prevent cases
where the last client's requests is always used to apply dual config rules.

When sending bandwidth requests to slave don't divide the request by
the number of ports as this is done at the RPM driver.

crypto: msm: multiple qce50 support

In some platforms such as fsm9900, multiple instances of qce50 hw
may be supported.  Each qce50 HW has an ndp-bam. Each qce50 HW
can support multiple instances of qce_dev platform device.
Each qce_dev has its own configured pipe set and associated qce50 HW,
defined by crypto-base and bam-pipe-pair fields in the device tree files.
This patch based on io address, it decides to create a new qce50 hw
instance or use the existing known instance at device probe time.

Furthermore, this patch does iomap for only once for each HW BAM instance
to avoid issue with bam driver. If modprobe, and rmmod of qcedev,
and qcrypto are not in first in last out order, kernel may crash in
bam driver in the last rmmod.
This saves virtual space for IO if multiple instances of qcedev
share the same instance of HW BAM.

crypto: msm: Fix issues related to non-zero byteoffset input

Fix buffer overflow for a non-zero byteoffset value.

Also fixes memory leak issue by adding data_len check in check_params.
One of the scenarios data_len can be less than byteoffset which results
in memory leak with huge data length, which might cause the kernel panic.

crypto: msm: qce50 ota crypto support

Kasumi/snow-3g f8/f9 are defined by 3gpp, as the algorithms for
UMTS, and LTE for over the air ciphering and integrity. The
algorithms are supported by crypto 5 hardware. This patch
enables qce50 driver to provide Kasumi/snow-3g f8/f9
ciphering and integrity services.
