Remove gdb-6.6-bz230000-power6-disassembly-test.patch

Browse Source 
Remove gdb-6.6-bz230000-power6-disassembly-test.patch as this is now
covered by upstream tests.  This patch added some tests of the Power6
disassembler.  Disassembler tests are better carried in the gas tree.

Upstream commit:

  commit 0fcf99b8ab5ccbde30fa7d36742e670cd4df48ef
  Date:   Mon Jan 30 11:47:31 2023 +0000

      gas/ppc: Additional tests for DFP instructions

Added some new assembler/disassembler tests to the gas tree that
covered all the instructions that were covered by our local patch.
