mimxrt: Add flash storage support with VFS and littlefs filesystem. This commit adds full support for a filesystem on all boards, with a block device object mimxrt.Flash() and uos.VfsLfs2 enabled. Main changes are: - Refactoring of linker scripts to accomodate reserved area for VFS. VFS will take up most of the available flash. 1M is reserved for code. 9K is reserved for flash configuration, interrupts, etc. - Addition of _boot.py with filesystem init code, called from main.c. - Definition of the mimxrt module with a Flash class in modmimxrt.[ch]. - Implementation of a flash driver class in mimxrt_flash.c. All flashing related functions are stored in ITCM RAM. - Addition of the uos module with filesystem functions. - Implementation of uos.urandom() for the sake of completeness of the uos module. It uses sample code from CircuitPython supplied under MIT license, which uses the NXP SDK example code. Done in collaboration with Philipp Ebensberger aka @alphaFred who contributed the essential part to enable writing to flash while code is executing, among other things.

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: Rework flash configuration. - Moves definition of BOARD_FLASH_SIZE and other header files related to flash configuration into the Makefile. - Adds board specific clock_config.h. - Adds board.h, pin_mux.h, and peripherals.h as they are required by NXP MCU SDK in order to use our own clock_config.h. - Renames board specific FlexSPI configuration files. - Updates flash frequency of MIMXRT1020_EVK - Creates separated flash_config files for QSPI NOR and QSPI Hyper flash. - Unifies VFS start address to be @ 1M for 1010 and 1020 boards. - Unifies 1050EVK boards - Adds support to both NOR and HyperFlash on boards with both capabilities. - Adds automatic FlexRAM initialization to start-up code based on linker script and NXP HAL. - Applies code formatting to all files in mimxrt port. With this change the flash configuration is restructured and organized. This simplifies the configuration process and provides a better overview of each board's settings. With the integration of clock_config.h, board.h, pin_mux.h, and peripherals.h we gain better control of the settings and clock configurations. Furthermore the implementation of an explicit FlexRAM setup improves the system performance and allows for performance tuning. Signed-off-by: Philipp Ebensberger

This commit includes: - add support for Hyperflash - modify MIMXRT1060_EVK and MIMXRT1064_EVK to change from QSPI to hyperflash. - minor incidental changes to other boards so they still build Note: Erasing a sector on the hyperflash is slow. It takes about a second, which seems too long, but matches the data sheet.
