[PATCH 1/3] dmaengine: dw-axi-dmac: fix Alignment should match open parenthesis

checkpatch.pl --strict reports a CHECK warning in dw-axi-dmac.c:

CHECK: Alignment should match open parenthesis

This warning occurs when multi-line function calls or expressions have
continuation lines that don't properly align with the opening
parenthesis position.

Fixes all instances in dw-axi-dmac.c where continuation lines were
indented with an inconsistent number of spaces/tabs that neither
matched the parenthesis column nor followed a standard indent pattern.
Proper alignment improves code readability and maintainability by
making parameter lists visually consistent across the kernel codebase.

Fixes: 0e3b67b348b8 ("dmaengine: Add support for the Analog Devices AXI-DMAC DMA controller")
Fixes: e3923592f80b ("dmaengine: axi-dmac: populate residue info for completed xfers")
Fixes: 3f8fd25936ee ("dmaengine: axi-dmac: Allocate hardware descriptors")
Fixes: 921234e0c5d7 ("dmaengine: axi-dmac: Split too large segments")
Fixes: a5b982af953b ("dmaengine: axi-dmac: add a check for devm_regmap_init_mmio")
