URL: https://github.com/apache/nuttx/pull/11845

   ## Summary
   AN12003: only one FlexNVM operation can be executed at a time.
   
   Disable ISR during FTFC operations so an ISR doesn't cause a hardfault from 
a simultaneous read.
   
   ## Impact
   arch/arm/src/s32k1xx/s32k1xx_progmem.c
   
   ## Testing
   Tested on a custom target based on the S32K148.
   Called printf and write to flash in a loop, no hardfault appears.
