spi: wpcm-fiu: Fix uninitialized res

Browse Source 
The second platform_get_resource_byname() can not be replaced with
devm_platform_ioremap_resource_byname(), because the intermediate "res"
is used by resource_size() later.

Fixes: 3bf2a5359b ("spi: wpcm-fiu: Use devm_platform_ioremap_resource_byname()")
