* Changes/fixes for drivers/cfi_flash.c:

Browse source 
- Add Intel legacy lock/unlock support to common CFI driver

    On some Intel flash's (e.g. Intel J3) legacy unlocking is
    supported, meaning that unlocking of one sector will unlock
    all sectors of this bank. Using this feature, unlocking
    of all sectors upon startup (via env var "unlock=yes") will
    get much faster.

  - Fixed problem with multiple reads of envronment variable
    "unlock" as pointed out by Reinhard Arlt & Anders Larsen.

  - Removed unwanted linefeeds from "protect" command when
    CFG_FLASH_PROTECTION is enabled.

  - Changed p3p400 board to use CFG_FLASH_PROTECTION

* Changes/fixes for drivers/cfi_flash.c:
  - Correctly handle the cases where CFG_HZ != 1000 (several
    XScale-based boards)
  - Fix the timeout calculation of buffered writes (off by a
    factor of 1000)
