[PATCH] soc: fsl: qbman: Remove redundant warnings

[Xiaolei Wang]

RESERVEDMEM_OF_DECLARE usage has been removed. For
non-popwerpc platforms, such as ls1043, this warning
is redundant. ls1043 itself uses shared-dma-mem.

Can you please explain in more details ? I don't understand what it is 
redundant with.

Thanks

commit 07f86917a450 used shared-dma-pool for QMan private memory 
allocations and

added this warning, but this is only for non-PPC platforms and using non 
shared-dma-mem

reservations. However, for non-PPC platforms, commit 3e62273ac63a will 
output a warning anyway.


At the same time, ls1043 already uses shared-dma-mem, so is this warning 
still necessary?


thanks
