Subject: [PATCH 2/2] serial: sh-sci: fix compilation breakage, when DMA is
 enabled

A recent commit:

commit d6fa5a4e7ab605370fd6c982782f84ef2e6660e7
Author: Guennadi Liakhovetski <g.liakhovetski@....de>
    serial: sh-sci: prepare for conversion to the shdma base library

is not sufficient to update the sh-sci driver to the new shdma driver
layout. This caused compilation breakage, when CONFIG_SERIAL_SH_SCI_DMA
is enabled. This patch trivially fixes the problem by updating the DMA
descriptor manipulation code.
