Use the generic error number instead of specific error number.
Changes fix the below error.

drivers/pci/pcie_dw_rockchip.c: In function 'rk_pcie_read':
drivers/pci/pcie_dw_rockchip.c:70:10: error: 'PCIBIOS_UNSUPPORTED'
			undeclared (first use in this function)
   70 |   return PCIBIOS_UNSUPPORTED;
      |          ^~~~~~~~~~~~~~~~~~~
drivers/pci/pcie_dw_rockchip.c: In function 'rk_pcie_write':
drivers/pci/pcie_dw_rockchip.c:90:10: error: 'PCIBIOS_UNSUPPORTED'

      |          ^~~~~~~~~~~~~~~~~~~
