usb: usbtmc: Add ioctl for termination character
add USBTMC_IOCTL_CONFIG_TERMCHAR to control TermChar handling
for next read(). Controls field 'TermChar' and Bit 1 of field
'bmTransferAttributes' of REQUEST_DEV_DEP_MSG_IN BULK-OUT header.
Allows enabling/disabling of terminating a read on reception of
term_char individually for each read request.
