qseecom: Add new IOCTLs to support secure UI feature

User space sends the buffer to TZ to use it for secure UI features.
Buffer shall be protected based on the use case, two APIs are
introduced to support this feature.

- QSEECOM_IOCTL_SEND_MODFD_RESP: is called to modify the listener
response data with physical address replaced at a mentioned offset,
so as to be usable by TZ. Option to protect &/ unprotect the buffer
is provided from user space (based on use case).

- QSEECOM_IOCTL_UNPROTECT_BUF: is called to explicitly unprotect the
protected buffer (use case specific).
