crypto: hisilicon - using 'debugfs_create_file' instead of 'debugfs_create_regset32'
The accelerator devices support runtime PM, when device is in suspended, an
exception will occur if reading registers. Therefore, this patch uses
'debugfs_create_file' instead of 'debugfs_create_regset32' to create
debugfs file, and then the driver can get the device status before
reading the register.
