ASoC: loongson: Fix build warning when !CONFIG_PCI

Fixes the below if kernel config disable PCI support:

sound/soc/loongson/loongson_i2s_pci.c:157:1: warning: data definition has no type or storage class
     157 | module_pci_driver(loongson_i2s_driver);
         | ^~~~~~~~~~~~~~~~~
sound/soc/loongson/loongson_i2s_pci.c:157:1: error: type defaults to 'int' in declaration of 'module_pci_driver' [-Wimplicit-int]
sound/soc/loongson/loongson_i2s_pci.c:157:1: error: parameter names (without types) in function declaration [-Wdeclaration-missing-parameter-type]
sound/soc/loongson/loongson_i2s_pci.c:149:26: warning: 'loongson_i2s_driver' defined but not used [-Wunused-variable]
     149 | static struct pci_driver loongson_i2s_driver = {
         |                          ^~~~~~~~~~~~~~~~~~~

Add the appropriate Kconfig dependency.
