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.
