[RFC 7/8] ARM:stih41x: Add B2000 board support

[Srinivas KANDAGATLA]

From: Srinivas Kandagatla <srinivas.kandagatla at st.com>

B2000 board is reference board for STIH415/416 SOCs, it has
2 x UART, 4x USB, 2 x Ethernet, 1 x SATA, 1 x PCIe, and 1GB RAM.

This patch add initial support to b2000 with STiH415/416 with UART2 as
console and a heard beat LED.
