IPU6 driver doesn't override the dma_ops of device now, it doesn't
depends on the ARCH_HAS_DMA_OPS, so remove the dependency in Kconfig.

dma_ops is removed from the IPU6 auxiliary device, ISYS driver
should use the IPU6 DMA mapping APIs directly instead of depending
on the device callbacks.
ISYS driver switch from the videobuf2 DMA contig memory allocator to
scatter/gather memory allocator.

DMA ops are a helper for architectures and not for drivers to override
the DMA implementation.
Unfortunately driver authors keep ignoring this. Make the fact more
clear by renaming the symbol to ARCH_HAS_DMA_OPS and having the two drivers
overriding their dma_ops depend on that. These drivers should probably be
marked broken, but we can give them a bit of a grace period for that.

Commit 4670c8c3fb ("media: ipu-bridge: Fix Kconfig dependencies") changed
how IPU_BRIDGE dependencies are handled for all drivers, but the IPU6
variant was added the old way, which causes build time warnings when I2C is
turned off:
WARNING: unmet direct dependencies detected for IPU_BRIDGE
Depends on [n]: MEDIA_SUPPORT [=m] && PCI [=y] && MEDIA_PCI_SUPPORT [=y] && (ACPI [=y] || COMPILE_TEST [=y]) && I2C [=n]
Selected by [m]:
- VIDEO_INTEL_IPU6 [=m] && MEDIA_SUPPORT [=m] && PCI [=y] && MEDIA_PCI_SUPPORT [=y] && (ACPI [=y] || COMPILE_TEST [=y]) && VIDEO_DEV [=m] && X86 [=y] && X86_64 [=y] && HAS_DMA [=y]
To make it consistent with the other IPU drivers as well as avoid this
warning, change the 'select' into 'depends on'.
