cpufreq: tegra194: remove opp table in exit hookcpufreq-arm-updates-6.6
Add exit hook and remove OPP table when the device gets unregistered.
This will fix the error messages when the CPU FREQ driver module is
removed and then re-inserted. It also fixes these messages while
onlining the first CPU from a policy whose all CPU's were previously
offlined.
debugfs: File 'cpu5' in directory 'opp' already present!
debugfs: File 'cpu6' in directory 'opp' already present!
debugfs: File 'cpu7' in directory 'opp' already present!
Fixes: f41e1442ac5b ("cpufreq: tegra194: add OPP support and set bandwidth")
