P2041RDB supports 3 sysclk frequencies, it's selected by SW1[6~8],
software need to read the SW1 status to decide what the sysclk needs.
SW1[8~6] : frequency
0 0 1 : 83.3MHz
0 1 0 : 100MHz
others: 66.667MHz

Add support for RGMII, SGMII and XAUI Ethernet on P2041RDB board.
The five dTSEC can be routed to two on-board RGMII phy, three on-board
SGMII phy or four SGMII phy on SGMII riser card according to different
serdes protocol configuration and board lane configuration. Also updated
the device tree to direct the Fmac MAC to the correct PHY.
Removed CONFIG_SYS_FMAN_FW as its not used anywhere.

Introduce the CONFIG_SYS_CCSRBAR_PHYS_HIGH and CONFIG_SYS_CCSRBAR_PHYS_LOW
macros, which contain the high and low portions of CONFIG_SYS_CCSRBAR_PHYS.
This is necessary for the assembly-language code that relocates CCSR, since
the assembler does not understand 64-bit constants.
CONFIG_SYS_CCSRBAR_PHYS is automatically defined from the
CONFIG_SYS_CCSRBAR_PHYS_HIGH and CONFIG_SYS_CCSRBAR_PHYS_LOW macros, so it
should not be defined in a board header file. Similarly,
CONFIG_SYS_CCSRBAR_DEFAULT is defined for each SOC in config_mpc85xx.h, so
it should also not be defined in the board header file.
CONFIG_SYS_CCSR_DO_NOT_RELOCATE is a "short-cut" macro that guarantees that
CONFIG_SYS_CCSRBAR_PHYS is set to the same value as CONFIG_SYS_CCSRBAR_DEFAULT,
and so CCSR will not be relocated.
Since CONFIG_SYS_CCSRBAR_DEFAULT is locked to a fixed value, multi-stage U-Boot
builds (e.g. NAND) are required to relocate CCSR only during the last stage
(i.e. the "real" U-Boot). All other stages should define
CONFIG_SYS_CCSR_DO_NOT_RELOCATE to ensure that CCSR is not relocated.
README is updated with descriptions of all the CONFIG_SYS_CCSRBAR_xxx macros.
