Mark Brown b661d753ce kselftest/arm64: Raise default number of loops in fp-pidbench
When fp-pidbench was originally written SVE hardware was not widely
available so it was useful to run it in emulation and the default number
of loops was set very low, running for less than a second on actual
hardware. Now that SVE hardware is reasonably available it is very much
less interesting to use emulation, bump the default number of loops up to
even out a bit of the noise on real systems. On the machine I have to hand
this now takes about 15s which is still a toy microbenchmark but perhaps a
bit more useful.

KSelfTest ARM64
===============

- These tests are arm64 specific and so not built or run but just skipped
  completely when env-variable ARCH is found to be different than 'arm64'
  and `uname -m` reports other than 'aarch64'.

- Holding true the above, ARM64 KSFT tests can be run within the KSelfTest
  framework using standard Linux top-level-makefile targets:

      $ make TARGETS=arm64 kselftest-clean
      $ make TARGETS=arm64 kselftest

      or

      $ make -C tools/testing/selftests TARGETS=arm64 \
		INSTALL_PATH=<your-installation-path> install

      or, alternatively, only specific arm64/ subtargets can be picked:

      $ make -C tools/testing/selftests TARGETS=arm64 ARM64_SUBTARGETS="tags signal" \
		INSTALL_PATH=<your-installation-path> install
