[PATCH v2 1/1] drivers/perf: thunderx2_pmu: Replace open coded acpi_match_acpi_device()

[Andy Shevchenko]

Replace open coded acpi_match_acpi_device() in get_tx2_pmu_type().

Signed-off-by: Andy Shevchenko <andriy.shevchenko at linux.intel.com>

v2:
switched to acpi_match_acpi_device() which is newer API suitable for this case
