Subject: [PATCH AUTOSEL 5.10 18/54] cpufreq: blacklist Arm Vexpress platforms in cpufreq-dt-platdev

From: Sudeep Holla <sudeep.holla@....com>

[ Upstream commit fbb31cb805fd3574d3be7defc06a7fd2fd9af7d2 ]

Add "arm,vexpress" to cpufreq-dt-platdev blacklist since the actual
scaling is handled by the firmware cpufreq drivers(scpi, scmi and
vexpress-spc).
