dmaengine: ti: k3-udma: Use cap_mask directly from dma_device structure instead of a local copy
commit 8ca9590c39b69b55a8de63d2b21b0d44f523b43a upstream.
Currently, a local dma_cap_mask_t variable is used to store device
cap_mask within udma_of_xlate(). However, the DMA_PRIVATE flag in
the device cap_mask can get cleared when the last channel is released.
This can happen right after storing the cap_mask locally in
udma_of_xlate(), and subsequent dma_request_channel() can fail due to
mismatch in the cap_mask. Fix this by removing the local dma_cap_mask_t
variable and directly using the one from the dma_device structure.
