doc: Tidy up the bindings for the config/ node

Browse source 
Sort these and add a type so it is clear how to set the value. Add a note
about usage to the top. Correct the 'no-keyboard' binding which is missing
a prefix.

@ -5,15 +5,15 @@ A number of run-time configuration options are provided in the /config node
of the control device tree. You can access these using fdtdec_get_config_int(),
fdtdec_get_config_bool() and fdtdec_get_config_string().
These options are designed to affect the operation of U-Boot at runtime.
Runtime-configuration items can help avoid proliferation of different builds
with only minor changes, e.g. enabling and disabling console output. Items
here should be those that can usefully be set by the build system after U-Boot
is built.
Available options are:
silent-console
If present and non-zero, the console is silenced by default on boot.
no-keyboard
Tells U-Boot not to expect an attached keyboard with a VGA console
u-boot,efi-partition-entries-offset
u-boot,efi-partition-entries-offset (int)
If present, this provides an offset (in bytes, from the start of a
device) that should be skipped over before the partition entries.
This is used by the EFI/GPT partition implementation when a device

If present (and supported by the specific board), indicates a
