FB queues handling is different from DMEM/EMEM queues in many aspects.
For e.g. no rewind required, additional queue struct fields, additional
queue operations required only for FB queues, push/pop semantics are
different.
Hence prepare separate structure and APIs for FB queues. PMU will have
to deal with the queue implementation chosen. This patch does the follo-
wing:
1. Update function/structure names to falcon_fb_queue_<op/name>.
2. Export nvgpu_falcon_fb_queue_* structure and functions.
3. Removed rewind function pointer and used direct functions for push,
pop and has_room.
4. PMU wrapper defined to use appropriate queue for empty check -
nvgpu_pmu_queue_is_empty.
5. PMU side updates for handling the work buffer and SEC2 updates for
usage of public queue functions.

MISRA Rule 10.1 states that operands shall not be of an
inappropriate essential type.
For example, the use of bitwise OR on signed values is not
permitted.
Both the pmu_read_message() and sec2_read_message() routines
do this in some cases when an error (or unexpected number of
bytes) is returned from the falcon queue pop/rewind routines.
This patch eliminates the MISRA violations by modifying these
cases to return the falcon queue operation error unmodified in the
corresponding status argument (or use -EINVAL in the event the
requested number of bytes isn't returned).
To reduce code duplication new pmu_falcon_queue_read() and
sec2_falcon_queue_read() routines are added here to wrap the
code that handles the error for the respective units.
Note that higher up in the call sequence (tu104_sec2_isr() in the
sec2_read_message() case and gk20a_pmu_isr() in the pmu_read_message()
case) the actual status value is only checked for non-zero or ignored
altogether. So it appears no existing code would depend on the
bitwise OR result anyway.
