powerpc/8xx: Remove left-over instruction and comments in DataStoreTLBMiss handler

Browse source

[ Upstream commit d9e46de4bf ]

Commit ac9f97ff8b ("powerpc/8xx: Inconditionally use task PGDIR in
DTLB misses") removed the test that needed the valeur in SPRN_EPN but
failed to remove the read.

Remove it.

And remove related comments, including the very same comment
in InstructionTLBMiss that should have been removed by
commit 33c527522f ("powerpc/8xx: Inconditionally use task PGDIR in
ITLB misses").

Also update the comment about absence of a second level table which
has been handled implicitely since commit 5ddb75cee5 ("powerpc/8xx:
remove tests on PGDIR entry validity").

Fixes: ac9f97ff8b ("powerpc/8xx: Inconditionally use task PGDIR in DTLB misses")
