Whether the Netsec driver is built to support coherent or non-coherent DMA is decided by the DmaLib library class resolution that is provided by the platform description, and there are various other places where the platform needs to be consistent with this (ACPI tables, device tree, platform driver, etc)
Since the driver has no way to figure out which flavor of DmaLib it was built against, there is no point in limiting it to one flavor only, and we can drop the DmaType check at binding time entirely. This fixes an issue introduced by commit 88c7874481b856578662b775 ("Silicon/SynQuacer/PlatformDxe: set NETSEC DMA as coherent"), which incorrectly stated that the driver does not look at the DmaType flag in the first place.
