This patch adds the necessary platform infrastructure code, so that the
MIPS Octeon drivers "serial_octeon_pcie_console" & "serial_bootcmd" can
be used. This is e.g. the bootmem initialization in a compatible way to
the Marvell 2013 U-Boot, so that the exisiting PC remote tools like
"oct-remote-console" & "oct-remote-load" can be used. This is be done in
the newly introduced arch_misc_init(), which calls the necessary init
functions when enabled.

These patches are in preparation for the MIPS Octeon NIC23 board
support, which is a desktop PCIe target board enabling these features.

This patch adds the PCI bootcmd feature for MIPS Octeon, which will be
used by the upcoming Octeon III NIC23 board support. It enables the use
of the "oct-remote-load" and "oct-remote-bootcmd" on host PC's to
communicate with the PCIe target and load images into the onboard
memory and issue commands.

As DEBUG is no Kconfig symbol, we can't use the IS_ENABLED() macros.
This patch switches to the unfortunately necessary #ifdef usage again
to make it work correctly.

This patch changes the MIPS Octeon defconfig to enable some features
for PCIe enablement. This includes CONFIG_BOARD_LATE_INIT to call the
board specific serdes init code.

With these features enabled, the serdes and PCIe driver including the
Intel E1000 driver can be tested on the Octeon EBB7304.

This patch adds the PCIe host controller driver for MIPS Octeon II/III.
The driver mainly consist of the PCI config functions, as all of the
complex serdes related port / lane setup, is done in the serdes / pcie
code available in the "arch/mips/mach-octeon" directory.

This patch adds the board specific QLM/DLM init code to the Octeon 3
EBB7304 board. The configuration of each port is read from the
environment exactly as done in the 2013 U-Boot version to keep the
board and it's configuration compatible.
