hal2.stm32f4.uvprojx doesn't compile with Keil compiler version 6

[valegagge]

I noticed that hal2.stm32f4.uvprojx compiles only with the compiler v5, while it returns 87 errors (due to cmsis) with the compiler v6.

Do we need to update the project?

There is no need to change the project because the hal2.stm32f4 uses ST Microelectronics code that is not compatible w/ compiler v6, so we have to stay w/ the v5 for it.

so we can close this issue.
