recipes: use https protocol and add explicit branch parameter

recipes: use https protocol and add explicit branch parameter

Due to https://github.blog/2021-09-01-improving-git-protocol-security-github/#no-more-unauthenticated-git
it is required to use https protocol for github repo accessing.

Update created with oe-core/scripts/contrib/convert-srcuri.py (see [0])

Fixes:

WARNING: /work/meta-freescale/recipes-bsp/u-boot/u-boot-fslc-mxsboot_2021.07.bb: URL: git://github.com/Freescale/u-boot-fslc.git;branch=2021.07+fslc uses git protocol which is no longer supported by github. Please change to ;protocol=https in the url.
