[B][SRU][PATCH 1/2] selftests/powerpc: Remove Power9 paste tests

[Po-Hsu Lin]

From: Michael Ellerman <mpe at ellerman.id.au>

BugLink: https://bugs.launchpad.net/bugs/1836715

Paste on POWER9 only works to accelerators and not on real memory. So
these tests just generate a SIGILL.

So just delete them.
