ARM: dts: meson8b: odroidc1: Fix the pwm regulator supply properties

Browse Source 
[ Upstream commit 876228e9f935f19c7afc7ba394d17e2ec9143b65 ]

After enabling CONFIG_REGULATOR_DEBUG=y we observe below debug logs.
Changes help link VCCK and VDDEE pwm regulator to 5V regulator supply
instead of dummy regulator.

[    7.117140] pwm-regulator regulator-vcck: Looking up pwm-supply from device tree
[    7.117153] pwm-regulator regulator-vcck: Looking up pwm-supply property in node /regulator-vcck failed
[    7.117184] VCCK: supplied by regulator-dummy
[    7.117194] regulator-dummy: could not add device link regulator.8: -ENOENT
[    7.117266] VCCK: 860 <--> 1140 mV at 986 mV, enabled
[    7.118498] VDDEE: will resolve supply early: pwm
[    7.118515] pwm-regulator regulator-vddee: Looking up pwm-supply from device tree
[    7.118526] pwm-regulator regulator-vddee: Looking up pwm-supply property in node /regulator-vddee failed
[    7.118553] VDDEE: supplied by regulator-dummy
