Thomas Fourier 6c0e9f05c9 pch_uart: Fix dma_sync_sg_for_device() nents value
The dma_sync_sg_for_device() functions should be called with the same
nents as the dma_map_sg(), not the value the map function returned
according to the documentation in Documentation/core-api/dma-api.rst:450:
	With the sync_sg API, all the parameters must be the same
	as those passed into the sg mapping API.

Fixes: da3564ee02 ("pch_uart: add multi-scatter processing")
