[PATCH 1/2] mtd: rawnand: fsmc: Reset NAND timings on resume()

[Linus Walleij <linus.walleij@xxxxxxxxxx>]

When we go through a suspend/resume cycle the NAND
timings may have been lost so reset the chip.

This hardware will autonomously enable/disable the
chip selects depending on what memory is accessed and
chip selects are not software controlled, so we
only lass chip select "0" for "all chips".
