Subject: arm64: dts: qcom: sc7180-trogdor: Fixup modem memory region
From: Sibi Sankar <sibis@xxxxxxxxxxxxxx>
commit ef9a5d188d663753e73a3c8e8910ceab8e9305c4 upstream.
The modem firmware memory requirements vary between 32M/140M on
no-lte/lte skus respectively, so fixup the modem memory region
to reflect the requirements.
