dw_axi_dma_set_hw_channel() logs "apb_regs not initialized" at err
level when apb_regs is absent. However, only Intel KeemBay
("intel,kmb-axi-dma") carries apb_regs; all other supported SoCs
(snps,axi-dma-1.01a, sophgo,cv1800b, starfive,jh7110/jh8100) operate
without it. For those, reaching this path during slave/cyclic prep and
terminate is the normal no-op case, not an error, and the err log spams
dmesg on every transfer.

Demote it to dev_dbg to match the identical check in
dw_axi_dma_set_byte_halfword().
