[PATCH v2 3/3] phy: rockchip-emmc: adapt binding to specifiy register offset and length

The emmc-phy occupies a contiguous set of 8 registers inside the general
register files, so the reg property should specify this.

This is essential a counter argument for Shawn's move from reg to reg_offset
in "phy: rockchip-emmc: fix compile issue on arm64 platform" [0].
With the move under the grf we now also are able to specify this stuff
cleanly using already present mechanisms.

Also meant to v4.6-rc before the binding solidifies.
