spi: remove struct spi_message::is_dma_mapped
There are no more users of the deprecated is_dma_mapped in struct
spi_message so it can be removed.
References in documentation and comments are also removed.
A few similar checks if xfer->tx_dma or xfer->rx_dma are not NULL are
also removed since these are now guaranteed to be NULL because they
were previously set only if is_dma_mapped was true.
