arm64: dts: qcom: sm8350-sagami: Add GPIO line names for TLMM

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 Sagami-common / PDX215 DTSIs to better document the
hardware.

Diff between 215 and common:
< 			  "NC",
< 			  "NC",
> 			  "WLC_I2C_SDA",
> 			  "WLC_I2C_SCL",
< 			  "NC",
> 			  "WLC_INT_N",
> 			  "CAM_MCLK4",
< 			  "NC",
< 			  "NC",
> 			  "TOF_RST_N",
< 			  "NC",
< 			  "NC",
< 			  "NC",
> 			  "QLINK1_REQ",
> 			  "QLINK1_EN",
> 			  "QLINK1_WMSS_RESET_N",

It's pretty logical as 1 III has WLC (WireLess Charging), and an
additional 3D iToF sensor. As for QLINK, no idea.
