Add support for ROHM BD7910[0,1,2,3] ADCs.

The ROHM BD79100, BD79101, BD79102 and BD79103 are ADCs derived from the
BD79104. According to the data-sheets, the BD79103 is compatible with the
BD79104. Rest of the ICs have different number of analog input channels.

This series adds support for these ICs using the ti-adc128s052.c.

NOTE: There has been work on couple of other patch series [1][2] touching
this same driver. I haven't considered those changes because, AFAICS,
there has been no new revisions of these series since mid June.
