Claudiu Beznea ee6dda36b4 soc: renesas: rz-sysc: Populate readable_reg/writeable_reg in regmap config 
[ Upstream commit c432180a7d ]

Not all system controller registers are accessible from Linux. Accessing
such registers generates synchronous external abort. Populate the
readable_reg and writeable_reg members of the regmap config to inform the
regmap core which registers can be accessed. The list will need to be
updated whenever new system controller functionality is exported through
regmap.
