pflash: Rename pflash_t to PFlashCFI01, PFlashCFI02

Browse Source 
flash.h's incomplete struct pflash_t is completed both in
pflash_cfi01.c and in pflash_cfi02.c.  The complete types are
incompatible.  This can hide type errors, such as passing a pflash_t
created with pflash_cfi02_register() to pflash_cfi01_get_memory().

Furthermore, POSIX reserves typedef names ending with _t.

Rename the two structs to PFlashCFI01 and PFlashCFI02.
