Jan Dabros 282d715133 soc/amd/common/block/i2c: Add support for shared TPM_I2C controller 
There are platforms equipped with AMD SoC where I2C3 controller
connected to TPM device is shared between X86 and PSP. In order to
handle this, PSP acts as an I2C-arbitrator, where x86 (kernel) sends
acquire and release requests to be accepted by PSP. An example of
implementation within Linux kernel is available [1].

There is a need to introduce new ACPI_ID ("AMDI0019") so that dedicated
driver on OS side can bind to it and handle this special setup. Since
PSP takes care of I2C controller power management, we need to remove
PowerResource object from DSDT.
