ACPI: APD: Check for NULL pointer after calling devm_ioremap()

Because devres_alloc() may fail, devm_ioremap() may return NULL.

Then, 'clk_data->base' will be assigned to clkdev->data->base in
platform_device_register_data().

The PTR_ERR_OR_ZERO() check on clk_data does not cover 'base', so
it is better to add an explicit check against NULL after updating
it.
