soc: fsl: qbman: Remove redundant warnings

This warning was added by commit 07f86917a450 ("soc/fsl/qbman: Use
shared-dma-pool for QMan private memory allocations") but
RESERVEDMEM_OF_DECLARE usage was removed by
commit 3e62273ac63a ("soc: fsl: qbman: Remove RESERVEDMEM_OF_DECLARE
usage") . For non-popwerpc platforms, such as ls1043, this warning
is redundant. ls1043 itself uses shared-dma-mem.

Fixes: 3e62273ac63a ("soc: fsl: qbman: Remove RESERVEDMEM_OF_DECLARE usage")
