A newer CPLD version on the 405EX evaluation board requires a different
EBC controller setup for the CPLD register access. This patch adds a CPLD
version detection for Kilauea and code to reconfigure the EBC controller
(chip select 2) for the old CPLD if no new version is found.

Additionally the CPLD version is printed upon bootup:

When the board is booted without serial cable attached (which
is how most of them will be used) UART RX is left floating and
sometimes picks noise, which interrupts countdown and enters
U-Boot prompt instead of booting the kernel.

Fix this by setting up internal pullup on UART RX pin. This
does not prevent serial from working as the internal pullup
is weak.

This patch fixes an ugly behavior of the IL712 magnetic coupler
as used on VOM405. These parts will remember their last state
over a power cycle which might cause unwanted behavior.

The same code exists both inside an #ifdef and outside of it.
Remove the extra code for all the 86xx boards.

This reverts commit 70ed869ea5f6b1d13d7b140c83ec0dcd8a127ddc.

There isn't any need to modify the API for fsl_pci_init_port to pass the
status of host/agent(end-point) status.  We can determine that
internally to fsl_pci_init_port.  Revert the patch that makes the API
change.
