targets:MIMXRT1050: Add QSPI Flash FLASHIAP support
Update the flash driver to support both Hyper Flash and QSPI Flash. In addition, the static function cannot be linked to SRAM even defined by AT_QUICKACCESS_SECTION_CODE macro. So remove all "static" modifier for the FLASHIAP functions. Signed-off-by: Gavin Liu <[email protected]>
