MAINTAINERS: Update STi and STM32 maintainers emails in remaining files

A previous series already update STMicroelectronics emails maintainers
but some files have been omitted (Makefile, .dts, .dtsi and .rst files).
Update Patrick and my email address with the one dedicated to upstream
activities.
