spi: atmel-quadspi: fix crash while suspending
[ Upstream commit e5c27498a0403b270620b1a8a0a66e3efc222fb6 ]
atmel_qspi objects are kept in spi_controller objects, so, first get
pointer to spi_controller object and then get atmel_qspi object from
spi_controller object.
Fixes: 2d30ac5ed633 ("mtd: spi-nor: atmel-quadspi: Use spi-mem interface for atmel-quadspi driver")
