[PATCH 5.12 199/677] arm64: dts: qcom: sm8350: fix number of pins in gpio-ranges

[ Upstream commit 790158579c8e663081e7d708d57e8ac6d69dca4e ]

The last cell of 'gpio-ranges' should be number of GPIO pins, and in
case of qcom platform it should match msm_pinctrl_soc_data.ngpio rather
than msm_pinctrl_soc_data.ngpio - 1.

This fixes the problem that when the last GPIO pin in the range is
configured with the following call sequence, it always fails with
-EPROBE_DEFER.

pinctrl_gpio_set_config()
pinctrl_get_device_gpio_range()
pinctrl_match_gpio_range()

Fixes: b7e8f433a673 ("arm64: dts: qcom: Add basic devicetree support for SM8350 SoC")
