phy: apple: apple: Use local variable for ioremap return value

The indirection through the resources array is unnecessarily complicated
and resuling in using IS_ERR() and PTR_ERR() on a valid address. A local
variable for the devm_ioremap_resource() return value is both easier to
read and matches expectations when reading code.
