arm64: dts: qcom: sm8450-nagara: Add GPIO line names for PMIC GPIOs 



Sony ever so graciously provides GPIO line names in their downstream
kernel (though sometimes they are not 100% accurate and you can judge
that by simply looking at them and with what drivers they are used).

Add these to the PDX223&224 DTSIs to better document the hardware.

Diff between 223 and 224:
pm8350b
< 			  "CAM_PWR_LD_EN",
> 			  "NC",

pm8350c
<			  "RGBC_IR_PWR_EN",
> 			  "NC",

Which is due to different camera power wiring on 223 and lack of a
ToF sensor on 224.
