[PATCH v4 1/5] w1: ds1wm: fix register offset (bus shift) calculation

Replace incorrect register offsett calculation by direct configuration of bus_shift in mfd-cell. Indirect definition of address-shift by resource size was unobvious and was wrong (should have used a binary log). Signed-off-by: Johannes Poehlmann <johannes.poehlm...@izt-labs.de> Acked-by: E
