dt-bindings: clock: ti: remove unstable remark

Several TI SoC clock bindings were marked as work-in-progress / unstable
between 2013-2016, for example in commit f60b1ea5ea7a ("CLK: TI: add
support for gate clock"). It was enough of time to consider them stable
and expect usual ABI rules.

Documentation/devicetree/bindings/clock/ti/adpll.txt

···
 Binding for Texas Instruments ADPLL clock.
 
-Binding status: Unstable - ABI compatibility may be broken in the future
-
 This binding uses the common clock binding[1]. It assumes a
 register-mapped ADPLL with two to three selectable input clocks
 and three to four children.

Documentation/devicetree/bindings/clock/ti/apll.txt

···
 Binding for Texas Instruments APLL clock.
 
-Binding status: Unstable - ABI compatibility may be broken in the future
-
 This binding uses the common clock binding[1].  It assumes a
 register-mapped APLL with usually two selectable input clocks
 (reference clock and bypass clock), with analog phase locked

Documentation/devicetree/bindings/clock/ti/autoidle.txt

···
 Binding for Texas Instruments autoidle clock.
 
-Binding status: Unstable - ABI compatibility may be broken in the future
-
 This binding uses the common clock binding[1]. It assumes a register mapped
 clock which can be put to idle automatically by hardware based on the usage
 and a configuration bit setting. Autoidle clock is never an individual

Documentation/devicetree/bindings/clock/ti/clockdomain.txt

···
 Binding for Texas Instruments clockdomain.
 
-Binding status: Unstable - ABI compatibility may be broken in the future
-
 This binding uses the common clock binding[1] in consumer role.
 Every clock on TI SoC belongs to one clockdomain, but software
 only needs this information for specific clocks which require

Documentation/devicetree/bindings/clock/ti/composite.txt

···
 Binding for TI composite clock.
 
-Binding status: Unstable - ABI compatibility may be broken in the future
-
 This binding uses the common clock binding[1]. It assumes a
 register-mapped composite clock with multiple different sub-types;
 

Documentation/devicetree/bindings/clock/ti/divider.txt

···
 Binding for TI divider clock
 
-Binding status: Unstable - ABI compatibility may be broken in the future
-
 This binding uses the common clock binding[1].  It assumes a
 register-mapped adjustable clock rate divider that does not gate and has
 only one input clock or parent.  By default the value programmed into

Documentation/devicetree/bindings/clock/ti/dpll.txt

···
 Binding for Texas Instruments DPLL clock.
 
-Binding status: Unstable - ABI compatibility may be broken in the future
-
 This binding uses the common clock binding[1].  It assumes a
 register-mapped DPLL with usually two selectable input clocks
 (reference clock and bypass clock), with digital phase locked

Documentation/devicetree/bindings/clock/ti/fapll.txt

···
 Binding for Texas Instruments FAPLL clock.
 
-Binding status: Unstable - ABI compatibility may be broken in the future
-
 This binding uses the common clock binding[1]. It assumes a
 register-mapped FAPLL with usually two selectable input clocks
 (reference clock and bypass clock), and one or more child

Documentation/devicetree/bindings/clock/ti/fixed-factor-clock.txt

···
 Binding for TI fixed factor rate clock sources.
 
-Binding status: Unstable - ABI compatibility may be broken in the future
-
 This binding uses the common clock binding[1], and also uses the autoidle
 support from TI autoidle clock [2].
 

Documentation/devicetree/bindings/clock/ti/gate.txt

···
 Binding for Texas Instruments gate clock.
 
-Binding status: Unstable - ABI compatibility may be broken in the future
-
 This binding uses the common clock binding[1]. This clock is
 quite much similar to the basic gate-clock [2], however,
 it supports a number of additional features. If no register

···
 Binding for Texas Instruments interface clock.
 
-Binding status: Unstable - ABI compatibility may be broken in the future
-
 This binding uses the common clock binding[1]. This clock is
 quite much similar to the basic gate-clock [2], however,
 it supports a number of additional features, including

···
 Binding for TI mux clock.
 
-Binding status: Unstable - ABI compatibility may be broken in the future
-
 This binding uses the common clock binding[1].  It assumes a
 register-mapped multiplexer with multiple input clock signals or
 parents, one of which can be selected as output.  This clock does not
