Philipp Ebensberger 0d7366c912 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.

robert-hh 1074c784b0 mimxrt: Add support for Hyperflash chips.
Hyperflash is used by the MIMXRT1050_EVKB, MIMXRT1060_EVK and
MIMXRT1064_EVK boards.

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.
