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.
