Subject: [PATCH 2/3] arm64: dts: qcom: sdm845-tama: 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 Akari, Apollo & Akatsuki DTS-es to better document
the hardware.

pm8005 and pm8998 config is common for all three boards.
Apollo has VIB_LDO_EN (replacing NC) on PMI8998_GPIO_5

Akari and Akatsuki have WLC_EN_N (replacing NC) on PMI8998_GPIO_8

Akari additionally has RSVD(WLC_EN_N) (replacing) on PMI8998_GPIO_11
which sounds a bit like a forgot-to-update-documentation, but maybe
it differs between SKUs.. Time will tell, when we get to enabling the
wireless charger.
