d790300215 spi_flash: fix stale data being read from mmaped region
The issue that cache entries are not invalidated correctly sometimes
can also be reproduced for non-encrypted flash as well.
This change updates the workaround to do Cache_Flush, enabling it for
non-encrypted flash, and adds a unit test.

d8aae55eeb 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.

36ccdee6ec 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.)
