Building U-Boot with CONFIG_PCI and CONFIG_DM_PCI enabled, but CONFIG_SPL_PCI_SUPPORT disabled, results in following linker error:
lib/built-in.o: In function `fdtdec_get_pci_bar32': lib/fdtdec.c:305: undefined reference to `dm_pci_read_bar32' fdtdec.c:305:(.text.fdtdec_get_pci_bar32+0x24): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `dm_pci_read_bar32'
This is because reference to dm_pci_read_bar32() remains in lib/fdtdec.c while SPL build does not descend into drivers/pci directory in drivers/Makefile if CONFIG_SPL_PCI_SUPPORT is not enabled.
Fix this by applying appropriate #define guards in lib/fdtdec.c. It looks like ns16550.c has the same problem, so fixed that too.
To simplify this, CONFIG_SPL_PCI_SUPPORT is renamed to CONFIG_SPL_PCI (enables use of CONFIG_IS_ENABLED() macro).
