when accessing /dev/tpm0 by tcti-device，if write failed, read will block at poll().

When opening tpm, the flag is set to O_NONBLOCK. https://github.com/tpm2-software/tpm2-tss/blob/512b90dd3a5b814ea4eca973b70e92538fd630c7/src/tss2-tcti/tcti-device.c#L384-L390 Therefore, when the tcti-device calls write(), it will directly return success, and the tpm driver will write the tpm asynchronously....

stack usage is too large when tcti initialize

Hi, teamer. When Tss2_TctiLdr_Initialize is executed, the tcti_from_file interface is called. In tcti_from_file, `PATH_MAX`(4KB) of stack space is malloced. Is there some problems for some resource-constrained embedded devices?

In tctildr.h, there are the duplicated declaration for 'tcti_from_info' https://github.com/tpm2-software/tpm2-tss/blob/d78b1267d605c313dddd56bcec192303dcde1c2a/src/tss2-tcti/tctildr.h#L35-L76
