This patch adds generic codes to support Freescale's Vybrid MVF600 CPU.
It aligns Vybrid MVF600 platform with i.MX platform. As there are some differences between MVF600 and i.MX platforms, the specific codes are in the arch/arm/cpu/armv7/mvf600 directory.

Changes in v3:
- Rename the common functions and enums
- Move the structure definitions to imx-regs.h
Changes in v2:
- Remove vybrid-common directory
- Rename directory name 'vybrid' to 'mvf600'
- Add generic.c file
- Rewrite get_reset_cause() to make it readable
- Remove reset_cpu(), and use the function in imx_watchdog.c
- Rewrite timer.c file
- Use vybrid_get_clock(VYBRID_UART_CLK) instead of vybrid_get_uartclk()
- Remove lowlevel_init.S, and add clock_init() in board_early_init_f()
- Remove useless CONFIG_SYS_ defines
- Move CONFIG_MACH_TYPE to board configuration file
- Define C structures and access C structures to set/read registers
- Remove useless errata
- Remove useless macros
- Rename directory 'arch-vybrid' to 'arch-mvf600'

Since this includes support for OCOTP on this SoC, the following hunks should also be added:
doc/README.mxc_ocotp: --- on MXC
This IP can be found on the following SoCs: + - Vybrid MVF600, - i.MX6.
Note that this IP is different from albeit similar to the IPs of the same name ---

CONVENTIONS FOR FUSE ASSIGNMENTS +----------------------------------- + +1.1 MAC Address: It is stored in fuse bank 4, with the 16 msbs in word 2 and the + 32 lsbs in word 3. ---
You can also add the definition of the fuses for UID if any, like uid_low/high in struct fuse_bank0_regs in arch/arm/include/asm/arch-mx6/imx-regs.h.
