arm64: dts: meson-g12b: Fix the pwm regulator supply properties

[ Upstream commit 62183863f708c2464769e0d477c8ce9f3d326feb ]

After enabling CONFIG_REGULATOR_DEBUG=y we observer below debug logs.
Changes help link VDDCP_A and VDDCPU_B pwm regulator to 12V regulator
supply instead of dummy regulator.

[    4.147196] VDDCPU_A: will resolve supply early: pwm
[    4.147216] pwm-regulator regulator-vddcpu-a: Looking up pwm-supply from device tree
[    4.147227] pwm-regulator regulator-vddcpu-a: Looking up pwm-supply property in node /regulator-vddcpu-a failed
[    4.147258] VDDCPU_A: supplied by regulator-dummy
[    4.147288] regulator-dummy: could not add device link regulator.12: -ENOENT
[    4.147353] VDDCPU_A: 721 <--> 1022 mV at 871 mV, enabled
[    4.152014] VDDCPU_B: will resolve supply early: pwm
[    4.152035] pwm-regulator regulator-vddcpu-b: Looking up pwm-supply from device tree
[    4.152047] pwm-regulator regulator-vddcpu-b: Looking up pwm-supply property in node /regulator-vddcpu-b failed
[    4.152079] VDDCPU_B: supplied by regulator-dummy
[    4.152108] regulator-dummy: could not add device link regulator.13: -ENOENT
