[PATCH 07/71] clocksource: sh_cmt: Add memory base to sh_cmt_channel structure

[Daniel Lezcano]

From: Laurent Pinchart <laurent.pinchart+renesas@xxxxxxxxxxxxxxxx>

The channel memory base is channel-specific, add it to the channel
structure in preparation for support of multiple channels per device.
