mimxrt/sdram: Add SDRAM support. 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

mimxrt: Add support for MIMXRT1176 MCUs, and MIMXRT1170_EVK board. The RT1176 has two cores, but the actual firmware supports only the CM7. There are currently no good plans on how to use the CM4. The actual MIMXRT1170_EVK board is on par with the existing MIMXRT boards, with the following extensions: - Use 64 MB RAM for the heap. - Support both LAN interfaces as LAN(0) and LAN(1), with LAN(1) being the 1GB interface. The dual LAN port interface can eventually be adapted as well for the RT1062 MCU. This work was done in collaboration with @alphaFred.

IOMUXC_SetPinMux(MIMXRT_IOMUXC_SEMC_DATA11, 0UL);
mimxrt: Add support for MIMXRT1176 MCUs, and MIMXRT1170_EVK board. The RT1176 has two cores, but the actual firmware supports only the CM7. There are currently no good plans on how to use the CM4. The actual MIMXRT1170_EVK board is on par with the existing MIMXRT boards, with the following extensions: - Use 64 MB RAM for the heap. - Support both LAN interfaces as LAN(0) and LAN(1), with LAN(1) being the 1GB interface. The dual LAN port interface can eventually be adapted as well for the RT1062 MCU. This work was done in collaboration with @alphaFred.

mimxrt/sdram: Add SDRAM support. 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`.

mimxrt: Add support for MIMXRT1176 MCUs, and MIMXRT1170_EVK board. The RT1176 has two cores, but the actual firmware supports only the CM7. There are currently no good plans on how to use the CM4. The actual MIMXRT1170_EVK board is on par with the existing MIMXRT boards, with the following extensions: - Use 64 MB RAM for the heap. - Support both LAN interfaces as LAN(0) and LAN(1), with LAN(1) being the 1GB interface. The dual LAN port interface can eventually be adapted as well for the RT1062 MCU. This work was done in collaboration with @alphaFred.
