Rename mx51 to mx5 in order to support more mx51 like-style SOCs such as MX53 and the followings.

Signed-off-by: Jason Liu r64343@freescale.com

--- Changes for v2:

Address the comments from Stefano Babic: - rebase - remove CONFIG_CPU_TYPE - remove copyright change - change vision2 board config

Changes for v3: Address the comments from Wolfgang Denk: - Change CONFIG_HCLK_FREQ to CONFIG_SYS_MX5_HCLK - Change CONFIG_CLK32 to CONFIG_SYS_MX5_CLK32 - Add "mx5" resp. "MX5" to the new identifier names.
