arch/arm/stm32h5: add missing I2C2/I2C4 pin remap options
Add 8 missing AF4 I2C2/I2C4 pin remap defines to
stm32h56xxx_pinmap.h, per ST's datasheet. Needed by boards that wire
I2C2/I2C4 to these pins; without them such configs fail to compile.
Reduced from a larger internal patch; the stm32_i2c.c part of that
patch is already upstream, so only this pinmap gap remained.
