This patch adds very basic minimal support for the Marvell Octeon 3 CN73xx based EBB7304 EVK. Please note that the basic Octeon port does not support DDR3/4 initialization yet. To still use U-Boot on with this port, the L2 cache (4MiB) is used as RAM. This way, U-Boot can boot to the prompt on this board.
Supported devices: - UART - reset - CFI parallel NOR flash

Changes in v3: - Remove inclusion of "common.h" - Slightly change some copyright messages (adjust year)
Changes in v2: - Removed CONFIG_SYS_MIPS_TIMER_FREQ
