STM32F746G-DISCO Unsupported

[pymaximus]

First of all, thanks for this project, it definitely helps my projects !!

Testing with a STM32 F7 Discovery board with STM32F746NGH6 MCU and cmake things its a 765xx device.

23:22 $ cmake -DSTM32_CHIP=STM32F746NG -DCMAKE_TOOLCHAIN_FILE=/Users/frank/other_repos/stm32-cmake/cmake/gcc_stm32.cmake -DCMAKE_BUILD_TYPE=Debug ../
-- No TARGET_TRIPLET specified, using default: arm-none-eabi
-- No STM32_FAMILY specified, trying to get it from STM32_CHIP
-- Selected STM32 family: F7
-- STM32F746NG is 765xx device

If I make the following change

diff --git a/cmake/gcc_stm32f7.cmake b/cmake/gcc_stm32f7.cmake

SET(STM32_CODES "745.." "746.." "756.." "767.." "777.." "769.." "779..")

ie: change the 765xx into 746xx in STM32_CHIP_TYPES then all is well.

The flash and ram sizes are correct for this chipset, according to the linker script provided by
STM32Cube
