staging: add missing SPDX lines to Kconfig files There are a few remaining drivers/staging/*/Kconfig files that do not have SPDX identifiers in them. Add the correct GPL-2.0 identifier to them to make scanning tools happy.

staging: Move ralink-gdma to its own directory This is in preparation to allow it and the mt7621-dma drivers to be built separately. They are completely independent pieces of software, and the Kconfig specifies very different requirements.

staging: ralink-gdma: fix kconfig dependency bug for DMA_RALINK [ Upstream commit 06ea594051707c6b8834ef5b24e9b0730edd391b ] When DMA_RALINK is enabled and DMADEVICES is disabled, it results in the following Kbuild warnings: WARNING: unmet direct dependencies detected for DMA_ENGINE Depends on [n]: DMADEVICES [=n] Selected by [y]: - DMA_RALINK [=y] && STAGING [=y] && RALINK [=y] && !SOC_RT288X [=n] WARNING: unmet direct dependencies detected for DMA_VIRTUAL_CHANNELS Depends on [n]: DMADEVICES [=n] Selected by [y]: - DMA_RALINK [=y] && STAGING [=y] && RALINK [=y] && !SOC_RT288X [=n] The reason is that DMA_RALINK selects DMA_ENGINE and DMA_VIRTUAL_CHANNELS without depending on or selecting DMADEVICES while DMA_ENGINE and DMA_VIRTUAL_CHANNELS are subordinate to DMADEVICES. This can also fail building the kernel as demonstrated in a bug report. Honor the kconfig dependency to remove unmet direct dependency warnings and avoid any potential build failures.
