e0cb96c4e3 drivers: flash: Refactor drivers to use shared init priority
Refactors all of the on-chip flash drivers to use a shared driver class
initialization priority configuration, CONFIG_FLASH_INIT_PRIORITY, to
allow configuring flash drivers separately from other devices. This is
similar to other driver classes like I2C and SPI.

The default is set to CONFIG_KERNEL_INIT_PRIORITY_DEVICE to preserve the
existing default initialization priority for most drivers.

Driver-specific options for SPI-based flash drivers are left intact
because they need to be initialized at a different priority than on-chip
flash drivers.

The delay will ensure last byte has been latched in before

This also change the method of reading status register from re-send
