Two MTD fixes for 4.1:

* readtest: the signal-handling code was clobbering the error codes we should
    be handling/reporting in this test, rendering it useless. Noticed by Coverity.
 
  * the common SPI NOR flash DT binding (merged for 4.1-rc1) is being revised,
    so let's change that before 4.1 is minted.
