[U-Boot] [PATCH v2] 86xx: Update CPU info output on bootup

[Peter Tyser]

- Update style of 86xx CPU information on boot to more closely
  match 85xx boards
- Fix detection of 8641/8641D
- Use strmhz() to display frequencies
- Display L1 information
- Display L2 cache size
- Fixed CPU/SVR version output

== Before ==
Freescale PowerPC
CPU:
    Core: E600 Core 0, Version: 0.2, (0x80040202)
    System: Unknown, Version: 2.1, (0x80900121)
    Clocks: CPU:1066 MHz, MPX: 533 MHz, DDR: 266 MHz, LBC: 133 MHz
    L2: Enabled
Board: X-ES XPedite5170 3U VPX SBC

== After ==
CPU:   8641D, Version: 2.1, (0x80900121)
Core:  E600 Core 0, Version: 2.2, (0x80040202)
Clock Configuration:
       CPU:1066.667 MHz, MPX:533.333 MHz
       DDR:266.667 MHz (533.333 MT/s data rate), LBC:133.333 MHz
L1:    D-cache 32 KB enabled
       I-cache 32 KB enabled
L2:    512 KB enabled
Board: X-ES XPedite5170 3U VPX SBC
