The GPIO mappings on the IQS variant differ from the CQ variants.
GPIO138 is connected to the RGMII1_RX_CTL pin rather than the NFC ESE
Secure IO pin; the latter is connected to GPIO49. This incorrect
reservation causes the probe of the second Ethernet port to fail:
shikra-tlmm 500000.pinctrl: error -EINVAL: pin-138 (5d20000.ethernet)
shikra-tlmm 500000.pinctrl: error -EINVAL: could not request pin 138
(GPIO_138) from group gpio138 on device 500000.pinctrl
qcom-ethqos 5d20000.ethernet: Error applying setting, reverse things back
Replace gpio138 with gpio49 in the reserved list.
Fixes: 779aead2dace ("arm64: dts: qcom: shikra: Add gpio-reserved-ranges to tlmm")
