media: lirc: remove LIRCCODE and LIRC_GET_LENGTH

Browse Source 
LIRCCODE is a lirc mode where a driver produces driver-dependent
codes for receive and transmit. No driver uses this any more. The
LIRC_GET_LENGTH ioctl was used for this mode only.

``LIRC_MODE_LIRCCODE``
This mode can be used for IR receive and send.
The IR signal is decoded internally by the receiver, or encoded by the
transmitter. The LIRC interface represents the scancode as byte string,
which might not be a u32, it can be any length. The value is entirely
driver dependent. This mode is used by some older lirc drivers.
The length of each code depends on the driver, which can be retrieved
with :ref:`lirc_get_length`. This length is used both
for transmitting and receiving IR.
