This patchset is for supporting pmic driver-mode on universal_c210 board.
It's using i2c-s3c24x0.c file. (Fixes some complier error issue.)
Remove the soft_i2c codes in universal.c.
It seems a deadcode because of no usage.
Before time, it had used the soft-i2c as gpio_request(), not using s3c24x0-i2c.c
(gpb6/7 were used the sda/scl.)
There is no reason not to use the s3c24x0-i2c.c

Enable the CONFIG_DM_PMIC and CONFIG_DM_PMIC_MAX8998.
s5pc210_universal board is using max8998 pmic.
To use the i2c/pmic driver model, enable these configurations.

Removes the codes of soft_i2c.
There is no usasge for universal_c210, also didn't define
CONFIG_SOFT_I2C_GPIO_SCL.
This code seems a dead code.
