Subject: [PATCH] powerpc: drop even more unused Kconfig symbols

When I submitted commit 6805ab6daa2b589fe3242d05ddc47a9dbb0c4eb1
("powerpc: drop unused Kconfig symbols") I apparently failed to notice
that my patch also made PREP_RESIDUAL and PPC_A2_DD2 unused. Drop these
now.

0) Untested.

1) I investigated these Kconfig files a bit and discovered that PPC_PREP
is marked BROKEN since v2.6.15, see commit
5be396b00ca0f2f769c55cf69bbd7c77451c925e ("powerpc: Mark PREP and
embedded as broken for now"). Though it's not my problem, this does
suggest PReP support can be removed entirely.

-	  Some PReP systems have residual data passed to the kernel by the
-	  firmware.  This allows detection of memory size, devices present and
-	  other useful pieces of information.  Sometimes this information is
-	  not present or incorrect, in which case it could lead to the machine 
-	  behaving incorrectly.  If this happens, either disable PREP_RESIDUAL
-	  or pass the 'noresidual' option to the kernel.

-	  If you are running a PReP system, say Y here, otherwise say N.
