pata: imx: add support of setting timings for PIO modes The controller is capable to operate in up to PIO4 mode, however before the change the driver relies on timing settings done by a bootloader for PIO0 mode only. The change adds more flexibility in PIO mode selection at runtime and makes the driver to work even if bootloader does not preset ATA timings.
