spi: atmel-quadspi: fix crash while suspending 

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: 2d30ac5ed6 ("mtd: spi-nor: atmel-quadspi: Use spi-mem interface for atmel-quadspi driver")
