But early_memremap routine works with normal pointers whereas __acpi_map_table expects pointers in iomem address space. This causes kernel test bot to fail while using the sparse tool. Fix the issue by using early_ioremap and similar fix done for __acpi_unmap_table.

This will not work for ACPI based systems causing the driver to fail to register the PMU overflow interrupt handler. Hence, change the code to use the standard interface to find the INTC node which works irrespective of DT or ACPI.
