Rename some function parameters to solve -Wshadow issue in SPI and EEPROM libraries

[marshfolx]

I think -Wshadow is a good feature to avoid silly mistakes, like:

void f() {
    bool flag = false;
    // some code
    if(condition) {
        bool flag = true;
    }
    // some more code
    if(flag) {
        // want to do something, but flag is never true
    }
}

I have wasted some time on my silliness recently. So I think it's good to have this warning turned on, and when I do it, SPI and EEPROM libraries make the compiler complain.

This PR just renames those parametes, nearly no cost.

Hi @marshfolx
and thanks for pointing an fixing this.
I've added an other fix see on STM32U3 series.
