Function twl4030_i2c_read() is like twl4030_i2c_read_u8() but instead of
single value it rather returns array of values.

At this point, and especially for boards and not drivers, just do the
conversion unilaterally.  Thanks!

Use twl4030_i2c_read(), i2c_get_chip_for_busnum() and remove
CONFIG_SYS_I2C.

Just minor comment.
Is there a reason not to touch twl4030_i2c_write_u8()?

Well, it is because I have no usage for twl4030_i2c_write() yet. So I have
not touched write functions.

This new twl4030_i2c_read() function is used in PATCH 2/2.
