hc32f460: Use correct USART for PH2/PB10 pins 

This fixes serial communication when selecting the PH2/PB10 pins.

The chip datasheet (not reference manual) assigns pins to one of two
communication function groups (`Func_Grp1/2`). Pins in group 1 have
access to USART1/2 while group 2 has access to USART3/4. PH2/PB10 belong
to group 2 so we now correctly use USART3 for them.
