From: Chris Packham <chris.packham@alliedtelesis.co.nz>
commit 64d14c6fe040361ff6aecb825e392cf97837cd9e upstream.
When the gpio-addr-flash.c driver was merged with physmap-core.c the code to store the current gpio_values was lost. This meant that once a gpio was asserted it was never de-asserted. Fix this by storing the current offset in gpio_values like the old driver used to.
