Subject: [PATCH 20/37] dt-bindings: pwm: apple,s5l-fpwm: Add t6020-fpwm
 compatible

The PWM controller on Apple's M2 Pro/Max SoCs behaves in the same way as
on previous M1 and M2 SoCs. Add its per SoC compatible.

At the same time fix the order of existing entries. The sort order logic
is having SoC numeric code families in release order, and SoCs within
each family in release order:

- t8xxx (Apple HxxP/G series, "phone"/"tablet" chips)
  - t8103 (Apple H13G/M1)
  - t8112 (Apple H14G/M2)
- t6xxx (Apple HxxJ series, "desktop" chips)
  - t6000/t6001/t6002 (Apple H13J(S/C/D) / M1 Pro/Max/Ultra)
  - t6020/t6021/t6022 (Apple H14J(S/C/D) / M2 Pro/Max/Ultra)

Note that SoCs of the t600[0-2] / t602[0-2] family share the
t6000 / t6020 compatible where the hardware is 100% compatible, which is
usually the case in this highly related set of SoCs.
