Bug description:
  [ Impact ]

  overlays/README is used by the 'dtoverlay' command to display info on
  available overlays and params.

  [ Test Case ]

  $ apt install libraspberrypi-bin
  $ dtoverlay -h uart0
  * Help file not found

  With the README present:
  $ dtoverlay -h uart0
  Name:   uart0

  Info:   Change the pin usage of uart0

  Usage:  dtoverlay=uart0,<param>=<val>

  Params: txd0_pin                GPIO pin for TXD0 (14, 32 or 36 -
  default 14)

          rxd0_pin                GPIO pin for RXD0 (15, 33 or 37 -
  default 15)

          pin_func                Alternative pin function - 4(Alt0) for 14&15,
                                  7(Alt3) for 32&33, 6(Alt2) for 36&37

  [ Where Problems Could Occur ]

  The output of the `dtoverlay` could be wrong but it's only
  informational so should have no negative impact.
