100-pin 1MB F412 (LQFP/UFBGA). Without this, boards using
STM32F412VGH6 have to select the 48-pin 512KB CE.
STM32_NGPIO is 113 rather than the real 81 I/Os because
STM32_NGPIO_PORTS is (N+15)>>4 and 81 yields six ports A-F, so
PH0/PH1 could not be configured. 113 matches ZG and gives A-H.
CE/ZG chip.h counts and the family HAVE_* list are corrected in
the same change: CE has no FSMC, the die has TIM6/7/9-14 and
SPI4/5, ZG USART is 4, I2S is 5. FSMC is only bonded on 100/144-pin,
so HAVE_FSMC is selected on VG/ZG and not on CE.
