i2c: xiic: Fix coding style issues

Most of these stuff are reported by checkpatch.
But fixes are:
- Incorrect indetation
- Missing blank line after variable declaration
- Additional ()
- Missing spaces around +
- Missing parenthesis when if has them
- Newlines
- Remove MODULE_ALIAS - none is really using it
