Subject: [PATCH 6/7] ARM:mstar: Add syscon node for "pmsleep" area

MStar v7 SoCs contain a region of registers that are in the always on
domain that the vendor code calls the "pmsleep" area.

This area contains registers for a broad range of functionality and
needs to be shared between drivers.

This patch adds a syscon node for the pmsleep area so that other
drivers can access registers in the area.
