spi: pxa2xx-pci: Replace enum with direct use of PCI IDs
Instead of creating an abstraction on top of PCI IDs, just use them directly. The corresponding enum can be dropped. Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Link: https://lore.kernel.org/r/20220225172350.69797-7-andriy.shevchenko@linux.intel.com Signed-off-by: Mark Brown <broonie@kernel.org>
