Provide basic documentation for some of the other flash drivers.

 avr ... looks incomplete, may work with one AVR8 microcontroller
 ecosflash ... can't find docs
 lpc288x ... an NXP part, driver seems lpc2888-specific
 ocl ... some arm7/arm9 thing, can't find docs
 pic32mx ... looks incomplete, for PIC32MX (MIPS 4K) devices
 tms470 ... for TI TMS470 parts

Still seems to be mostly arm7tdmi... several of these have no
users in the current tree.
