This reverts commit d9a3bec682f9756621615f4306718a356a3230e3.
While this is a correct change to do long term it unfortunately breaks a
number of platforms that are using pdata and not named struct members so
they are getting all of their data after 'base' incorrect.

Enabling this driver requires some DT changes.
Adding DCC to root or main bus:
dcc: dcc {
compatible = "arm,dcc";
u-boot,dm-pre-reloc;
};
Extend alias list to link DCC:
serial0 = &uart0;
serial1 = &uart1;
serial2 = &dcc;
Change stdout-path to point to dcc port.
stdout-path = "serial2:115200n8";
Also add support for debug uart to help with early debug.

Use the driver model version of the function to find the BAR. This updates
the fdtdec function, of which ns16550 is the only user.
The fdtdec_get_pci_bdf() function is dropped for several reasons:
- with driver model we should use 'struct udevice *' rather than passing the
device tree offset explicitly
- there are no other users in the tree
- the function parses for information which is already available in the PCI
device structure (specifically struct pci_child_platdata which is available
at dev_get_parent_platdata(dev)

Change reg-shift property default to zero. When the integer property
is missing, it should be taken as zero. This is consistent to Linux
drivers/tty/serial/of_serial.c.
The x86 and most powerpc use reg-shift of 0. Most others use reg-shift
of 2. While reg-shift of 1 is rarely used.
