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.

This fixes boot of the modem on trogdor boards with the DTS from 5.10.y
stable tree. Without this patch I run into memory assignment errors and
then the modem fails to boot.

You forgot to sign off on this patch you forwarded on for stable
inclusion :(

Please fix up and resend if you wish to see it applied.
