Dave Hylands 7c934ae501 stmhal: Add hal and cmsis files from STM32Cube_FW_F7_V1.1.0. 
All files were converted to linux line endings.
All trailing whitespace was removed using:
for f in f7/inc/* f7/src/*; do sed --in-place 's/[[:space:]]\+$//' $f; done
All non-ascii chars in comments were replaced with ascii equivalents or
removed.
