hwmon: (zl6100) Enable interval between chip accesses for all chips
Intersil reports that all chips supported by the zl6100 driver require an interval between chip accesses, even ZL2004 and ZL6105 which were thought to be safe. Reported-by: Vivek Gani <vgani@intersil.com> Cc: stable@vger.kernel.org # 3.2+ Signed-off-by: Guenter Roeck <guenter.roeck@ericsson.com>
