Fix: nommu I2C adapter relocation error
NoMMU systems have a access violation problem with i2c_reloc_fixup.
Blame for it is a double relocation of the adapter itself. The
i2c_adap_p is already relocated, if i2c_reloc_fixup is called.
This patch removes the relocation of i2c_adap_p from i2c_reloc_fixup
to fix this.
