spi: spi-amd: Fix a NULL vs IS_ERR() check in amd_spi_probe() 
In case of error, the function devm_ioremap_resource() returns ERR_PTR()
and never returns NULL. The NULL test in the return value check should
be replaced with IS_ERR().

Fixes: bbb336f39efc ("spi: spi-amd: Add AMD SPI controller driver support")
