mtd: rawnand: meson: use a void pointer for meson_nfc_dma_buffer_setup
This simplifies the code because it gets rid of the casts to an
u8-pointer when passing "info_buf" from struct meson_nfc_nand_chip.
Also it gets rid of the cast of the u8 databuf pointer to a void
pointer.
The logic inside meson_nfc_dma_buffer_setup() doesn't care about the
pointer types themselves because it only passes them to dma_map_single
which accepts a void pointer.
No functional changes.
