stm32/boards: Swap FMC banks on ARDUINO_GIGA and ARDUINO_PORTENTA_H7.
Swap FMC banks to remap the SDRAM bank1 address to 0x60000000. Arduino's
M4 firmware uses address 0x60000000 by default. When the elf loader tries
to load that it will fail because by default NOR/PSRAM is mapped at that
address, not SDRAM bank1. (Note that the region at 0xC0000000 has an XN
attribute by default, so switching the M4 firmware address will not work.)
