Axel Lin 25d9507147 mfd: Remove unneeded ret value checking for max8998 register updates
i2c_smbus_write_byte_data() returns zero or negative value,
therefore no need to check if ret is greater than zero or not.

Joonyoung Shim 676e02d7a2 mfd: Use i2c_client as an argument on MAX8998 i2c routines
The MAX8998 chip have regulator and rtc features. The i2c slave address
of regulator and rtc is different, so needs each i2c client on i2c
operation functions.

Also, this patch exports i2c operation functions instead of callback to
make easy to read.
