Rob Herring 9f3849be6f dt-bindings: mfd: ti,j721e-system-controller: Fix mux node errors
The ti,j721e-system-controller binding does not follow the standard mux
controller node name 'mux-controller' and the example is incomplete. Fix
these to avoid schema errors before the mux controller binding is
converted to schema.

title: TI J721e System Controller Registers R/W Device Tree Bindings
description: |
This represents the Control Module registers (CTRL_MMR0) on the SoC.
System controller node represents a register region containing a set
of miscellaneous registers. The registers are not cohesive enough to
represent as any specific type of device. The typical use-case is
for some other node's driver, or platform-specific code, to acquire
a reference to the syscon node (e.g. by phandle, node path, or
search using a specific compatible value), interrogate the node (or
associated OS driver) to determine the location of the registers,
and access the registers directly.
