arm: dts: qcom: Sync pinctrl DT nodes with Linux bindings

Browse Source 
Currently for all Qcom SoCs/boards there are separate compatibles for
GPIO and pinctrl. But this is inconsistent with official (upstream) Linux
bindings which requires only a single compatible "qcom,<SoC name>-pinctrl"
and there is no such compatible property as "qcom,tlmm-<SoC name>".

So fix this inconsistency for Qcom SoCs in order to comply with upstream
DT bindings. This is done via removing compatibles from "msm_gpio" driver
and via binding to "msm_gpio" driver from pinctrl driver in case
"gpio-controller" property is specified for pinctrl node.
