Touchpad on sereval Lenovo ThinkBook doesn't work.

Maintain method calling ordering by calling _REG before issuing _STA, as
ACPI spec suggested, for I2C ACPI devices.

Positive feedback from several users.

[Regression Potential]
If there are some systems that rely on the wrong calling ordering then
there's a regression risk. However it's rather unlikely.

  i2c: core: Call i2c_acpi_install_space_handler() before
