nxp: add flexspi driver support
Flexspi driver now introduces read/write/erase APIs for complete flash
size, FAST-READ are by default used and IP bus is used for erase, read
and write using flexspi APIs.
Framework layer is currently embedded in driver itself using flash_info
defines.
Test cases are also added to confirm flash functionality currently under
DEBUG flag.
