2752654043 spi_flash: fix stale read issue for memory mapped partition
On flash program operation (either erase or write), if corresponding address has
cache mapping present then cache is explicitly flushed (for both pro and app cpu)

Closes https://github.com/espressif/esp-idf/issues/2146

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.)
