hw: Use PFLASH_CFI0{1,2} and TYPE_PFLASH_CFI0{1,2}

We have two open-coded copies of macro PFLASH_CFI01().  Move the macro
to the header, so we can ditch the copies.  Move PFLASH_CFI02() to the
header for symmetry.

We define macros TYPE_PFLASH_CFI01 and TYPE_PFLASH_CFI02 for type name
strings, then mostly use the strings.  If the macros are worth
defining, they are worth using.  Replace the strings by the macros.
