Subject: [PATCH v7 01/24] mfd: Add ingenic-tcu.h header

This header contains macros for the registers that are present in the
regmap shared by all the drivers related to the TCU (Timer Counter Unit)
of the Ingenic JZ47xx SoCs.

Notes:
     v2: Use SPDX identifier for the license
    
     v3: - Use macros instead of enum
         - Add 'TCU_' at the beginning of each macro
    	 - Remove useless include <linux/regmap.h>
    
     v4: No change
    
     v5: No change
    
     v6: Rename barrier macro from __LINUX_CLK_INGENIC_TCU_H__ to
         __LINUX_MFD_INGENIC_TCU_H__
    
     v7: No change
