  1. imxrt-flash: fast read fix for ISSI NOR flash 

    ISSI NOR chips use selecteble dummy cycles to support fast read command.
For 133 MHz fast read should include 11 dummy cycles (default is 6). To
set correct number of dummy cycles:

 - FCFB and flexspi_init() use 60 MHz clock and normal read
 - add custom ISSI commands and nor_issiInit()
 - add flexspi_postinit() which switches to final 133 MHz clock

DONE: RTOS-128
