[U-Boot] [PATCH V3 0/7] dm: universal_c210: support the DM_PMIC

[Jaehoon Chung]

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
