Stephanos Ioannidis 2a710b1372 Revert "drivers: dma: sam0: fix DMA to peripheral transfer on SAMD5x" ... This reverts commit 90cc723e65. Using `DMAC_CHCTRLA_TRIGACT_BLOCK` breaks SERCOM UART peripheral DMA operations (DMA-based asynchronous UART transmit operation only sends the first byte and does not proceed any further). The `DMAC_CHCTRLA_TRIGACT_BURST` with `DMAC_CHCTRLA_BURSTLEN(0)` is a special case utilising the "internal FIFO", according to the datasheet (see DS60001507E; 22.6.2.8), and should always be specified for peripheral data transfer operations. Also it is worth noting that Atmel and other third-party drivers use the aforementioned "internal FIFO" configuration for peripheral data transfers as well.
