6e2e26984f tzcom: Add support for modifying specific fields in cmd_buf
Allow client to send information to replace a specific field of
the cmd buffer with the physical address.  This is done via a new
IOCTL, TZCOM_IOCTL_SEND_CMD_FD_REQ, which is used to import the
ion fd handle. This IOCTL takes in a new send_cmd_fd_op_req
structure that has the same format as send-cmd_op_req with a
new field added: an array of ion handles (ifd_data.fd) and
cmd_buf_offset.

The client sends in an array of ion fd handle along with the
offset to the command buffer field.

This new IOCTL allows a client to send information regarding
which field(s) (at cmd_buf_offset) in the cmd_buf to replace.
These field(s) are replaced with the physical addr of the
buffer addressed by the respective ifd_data.fd handle.
