[PATCH -next 1/2] spi: atmel-quadspi: Fix uninitialized res

[Jinjie Ruan]

The second platform_get_resource_byname() can not be replaced with
devm_platform_ioremap_resource_byname(), because the intermediate "res"
is used to assign for "aq->mmap_size".

Fixes: 3ccea1dedef3 ("spi: atmel-quadspi: Simpify resource lookup")
