Dear Paul Burton,
This patch adds support for running on Malta boards using coreFPGA6 core cards, including support for the msc01 system controller used with them. The system controller is detected at runtime allowing one U-boot binary to run on a Malta with either.
Due to the PCI I/O base differing between Maltas using gt64120 & msc01 system controllers, the UART setup is modified slightly. A second UART is added so that there is one pointing at the correct address for each system controller. The Malta board then defines its own default_serial_console function to select the correct one at runtime. The incorrect UART will simply not function.
Tested on:
- A coreFPGA6 Malta running interAptiv and proAptiv bitstreams, both with and without an L2 cache.
- QEMU.

Changes in v3:
- rebase atop master
- remove commit message note about not working in QEMU, this does work in older QEMU versions as noted by Gabor Juhos
Changes in v2:
- rebased after malta moved to board/imgtec/malta
- removed unused status variable from msc01_config_access
