[STM32] DTCM buffer incorrect sized for processor type
port-stm32
In flashbdev.clocation and below the used DTCM is 64kByte, however the STM32F76xxx and STM32F77xxx feature a DTCM of 128kByte, whereas the STM32F75xx and STM32F74xx have a 64kByte DTCM.

Probably nobody cares, but flash is now filled for DEBUG=1 MICROPY_PY_WIZNET5K=1 MICROPY_PY_CC3K=1 build
I happened to have that particular combination as one of my travis builds, and that build now fills the flash (starting with commit c38809e26b71c539584462c2d02b6cd2647ade5b)
It looks like for PYBV10 that this is an artificial failure. The .ld file says that there is only 512K flash, but the STM32F405RGT6 (used on the PYBV10) actually has 1024K of flash.
