[PATCH 1/3] perf tests test_arm_coresight: Fix the shellcheck warning in latest test_arm_coresight.sh

[Athira Rajeev <atrajeev@linux.vnet.ibm.com>]

Running shellcheck on tests/shell/test_arm_coresight.sh
throws below warnings:

	In tests/shell/test_arm_coresight.sh line 15:
	cs_etm_path=$(find  /sys/bus/event_source/devices/cs_etm/ -name cpu* -print -quit)
                  ^--^ SC2061: Quote the parameter to -name so the shell won't interpret it.

	In tests/shell/test_arm_coresight.sh line 20:
		if [ $archhver -eq 5 -a "$(printf "0x%X\n" $archpart)" = "0xA13" ] ; then
                	             ^-- SC2166: Prefer [ p ] && [ q ] as [ p -a q ] is not well defined

This warning is observed after commit:
"commit bb350847965d ("perf test: Update cs_etm testcase for Arm ETE")"

Fixed this issue by using quoting 'cpu*' for SC2061 and
using "&&" in line number 20 for SC2166 warning

Fixes: bb350847965d ("perf test: Update cs_etm testcase for Arm ETE")
