Driver has a bug in that it uses rflow_in_use bitmap when setting up free rflow range
from TISCI but use rflow_map for reservation in __udma_reserve_rflow()

Fix this by dropping rflow_in_use bitmap array and use rflow_map for
PKTDMA. BCDMA does not need rflow_in_use either.

This fixes CPSW3g not able to get DMA channels at R5 SPL on AM64x

Somewhere along the way, someone misspelt "invalid" and it got copied
everywhere. Fix it.

Move the main option for handling drivers/dma/keystone_nav* to Kconfig,
and enable it by default.  All of the sub-symbols are not configurable,
so remove them from the CONFIG namespace.

This rule should not be in the top-level Makefile. Move it, making use
of the new LEGACY_DMA Kconfig.

This converts the following to Kconfig:
   CONFIG_DMA_LPC32XX

We cannot use the existing DMA config for the MCD driver because it is
not migrated to driver model. In order to move it to drivers/Makefile
we need some sort of option for it. Add a new DMA_LEGACY option, which
also acts as a signal that it should be migrated.

Enable this for devkit3250 which uses CONFIG_DMA_LPC32XX which is not
converted to Kconfig.

For now this is not used in the Makefile. That update happens in a
following patch.

These symbols are now either unused or were only used within the config
file to determine other logic, which could be done in a way that doesn't
further pollute the CONFIG namespace.
