18962: pkg/lwip: Force loglevel when using log module r=maribu a=yarrick
18999: Paho: Allow building for 8 and 16 bit platforms r=maribu a=OlegHahm
### Contribution description
Providing a patch to Paho upstream which uses fixed size integers (int32_t) instead of plain int whenever it is used to represent a size of an object.
This patch will allow to build the Paho package for platforms where an integer has a width of less than 32 bit.
This patch is also provided as a PR to the upstream version of Paho (https://github.com/eclipse/paho.mqtt.embedded-c/pull/238) but unfortunately the upstream seems to be unmaintained.
### Testing procedure
Build for a 8 or 16 bit platform that has enough memory for the example, e.g., https://api.riot-os.org/group__boards__atxmega-a1u-xpro.html:
BUILD_IN_DOCKER=1 BOARD=atxmega-a1u-xpro make clean all
Without this PR this build will fail, with the patches applied it will succeed.
### Issues/PRs references
This PR makes #18997 obsolete and thus reverts the change.

stm32mp157c-dk2 has not enough memory to build this apps.
However as the stm32mp157xx cpu line has no flash, a part of RAM
is considered as ROM. Thus ROM size could be extend to suit this
apps needs.
