Subject: [PATCH v1] arm64: dts: qcom: HAMOA-IOT-SOM: Unreserve GPIOs blocking SPI11 access

GPIOs 44-47 were previously reserved, preventing Linux from accessing
SPI11 (qupv1_se3). Since there is no TZ use case for these pins on Linux,
they can be safely unreserved. Removing them from the reserved list
resolves the SPI11 access issue for Linux.
