arm64: dts: qcom: sm8350-sagami: 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 PDX213&214 DTSIs to better document the hardware.

Diff between 223 and 224:

pm8350b
< 	gpio-line-names = "NC", /* GPIO_1 */
> 	gpio-line-names = "CAM_PWR_A_CS", /* GPIO_1 */
< 			  "NC",
> 			  "CAM_PWR_LD_EN",

pm8350c
< 			  "NC",
> 			  "WLC_TXPWR_EN",

Which is due to different camera power wiring on 213 and lack of an
additional SLG51000 PMIC on 214.
