Adding support for ht32f1755 ?

[FabienTregan]

Hi,

I wanted to try porting QMK to a cooler master rapid-i keyboard which uses a ht32f1755. QMK using chibios and chibios contrib already having support for ht32f1655.

I've done some cortex development but mainly on stm32's using rust and assembly. I could find short (45 pages) datasheets for the ht32f165x ans ht32f175x but could not find any difference except the flash / ram amount and some additional peripherals that are probably not needed by QMK. But I don't know if I can just compile for the 165x and use the code on the 175x ?

Is there a better place than an issue here to discuss the port ?
