TPMStateISA embeds the struct and inherits from the ISADevice. The prototype of functions bound to be used by both the ISA and SysBus devices is changed to take TPMState handle. A bunch of structs also are renamed to be specialized for the ISA device. Besides those transformations, no functional change is expected.

Only the main() will change (instantiation option is different). Also the base address of the TPM-TIS device is going to be different. on x86 it is located at 0xFED40000 while on ARM it can be located at any location, discovered through the device tree description. So we put shared test functions in a new object module. Each test needs to set tpm_tis_base_addr global variable. Also take benefit of this move to fix "block comments using a leading */ on a separate line" checkpatch warnings.
