Adds support for SDRAM via `SEMC` peripheral. SDRAM support can be enabled in the mpconfigboard.mk file by setting `MICROPY_HW_SDRAM_AVAIL` to `1` and poviding the size of the RAM via `MICROPY_HW_FLASH_SIZE`. When SDRAM support is enabled the whole SDRAM is currently used used for MicroPython heap. Signed-off-by: Philipp Ebensberger
