Flash encryption: Temporary fix for issue with stale cache reads
...
Seems doing certain kinds of short reads while flash encryption is
enabled will return stale data. This fixes it, but is probably a
little heavy-handed performance wise.

spi_flash: Flush flash cache if flash_mmap()ing a written-to page
...
Without this, it's possible for stale information to be read from
cache via mmap, even if the MMU table entry had been invalidated
prior to writing flash (if the same MMU table entry was re-used after
writing flash.)
