dt-bindings: soc/microchip: add info about services to mpfs sysctrl

Browse Source 
The services actually provided by the system controller are not
documented so add some words about what the system controller can
actually do. Add a link to the oneline documentation with the specific
details of each individual service.
Also, drop the unneeded label from the example.

The PolarFire SoC system controller is communicated with via a mailbox.
This document describes the bindings for the client portion of that mailbox.
PolarFire SoC devices include a microcontroller acting as the system controller,
which provides "services" to the main processor and to the FPGA fabric. These
services include hardware rng, reprogramming of the FPGA and verfification of the
eNVM contents etc. More information on these services can be found online, at
https://onlinedocs.microchip.com/pr/GUID-1409CF11-8EF9-4C24-A94E-70979A688632-en-US-1/index.html
Communication with the system controller is done via a mailbox, of which the client
portion is documented here.
