ata: pata_pxa: use devres for DMA channel management

Convert the DMA channel request to devm_dma_request_chan() so the
channel is released automatically on device teardown. This removes
the explicit dma_release_channel() calls in the probe error paths
and in pxa_ata_remove(), simplifying the driver.

Use ata_platform_remove_one() which is now equivalent to what remains of
the remove function after dma_release_channel() removal.

Built as a module for arm/pxa_defconfig (CONFIG_PATA_PXA=m) with
LLVM=1 W=1; no new warnings.
