Yogesh Mantri 2e02ed8484 feat(sdmmc): add dma_burst_size config, fix DMA to PSRAM on esp32p4 ...

FIFOTH.dma_multiple_transaction_size was never programmed and kept its
reset value of 0, which selects 1-byte DMA bursts. On esp32p4 with flash
encryption enabled those bursts do not reach PSRAM.

Add sdmmc_ll_set_dma_burst_size() and a dma_burst_size field in
sd_host_sdmmc_cfg_t, 0 selecting the per-target default. esp32p4
defaults to 16 bytes; esp32 and esp32s3 keep their current 1 byte.
