ata: libahci_platform: Parse ports-implemented property in resources getter
The ports-implemented property is mainly used on the OF-based platforms with no ports mapping initialized by a bootloader/BIOS firmware. Seeing the same of_property_read_u32()-based pattern has already been implemented in the generic AHCI LLDD (glue) driver and in the Mediatek, St AHCI drivers let's move the property read procedure to the generic ahci_platform_get_resources() method. Thus we'll have the forced ports mapping feature supported for each OF-based platform which requires that, and stop re-implementing the same pattern in there a bit simplifying the code.
