[PATCH 6.12.y-cip 01/18] clk: renesas: cpg-mssr: Simplify pointer math in cpg_rzt2h_mstp_read()

commit 21c1d66a1672573c1934734570bd3b05a301af9e upstream.

Private state is available in all places where cpg_rzt2h_mstp_read() is
called, remove the extra pointer math used to find it from clk_hw.

While at it, put these statements on a single line as they do not exceed
the 80 columns limit.
