p54spi: fix incorrect access sequence to DMA_WRITE_CTRL in p54spi_spi_write_dma

Browse source

Host is not allowed to modify DMA_WRITE_CTRL register
if bit HOST_ALLOWED in it is not set. Wait for HOST_ALLOWED first.

Also get rid of timeout in p54spi_wait_bit as it's been playing
a role of workaround for such an incorrect register access.
