The MAX77620 doesn't support bulk writes, so make sure the regmap code
breaks bulk writes into multiple single-byte writes.
Note that this is mostly cosmetic because currently only the RTC sub-
driver uses bulk writes and the RTC driver ends up using a different
regmap on the MAX77620 anyway. However, it seems like a good idea to
make this change now in order to avoid running into issues if bulk
writes are ever used by other sub-drivers sometime down the road.
