norflash: Clear status register before sending commands

The status register bits remain until explicitly cleared, which means
that a command can be incorrectly considered to have generated an error -
for example, after reset the status register contents may be unknown or
if a previous command had failed.

This patch clears the status register before beginning any command to
be sure that the status register only represents information about the
current operation.
