[PATCH 19/67 v2] staging: comedi: pcl818: fix PCL818_FI_DATAHI

The A/D FIFO uses two registers to get each analog data sample.
PCL818_FI_DATALO is the LSB of the data and PCL818_FI_DATAHI is
the MSB of the data. The current define for PCL818_FI_DATAHI is
incorrect and results in the LSB getting read twice.
