clk: renesas: Only ever access documented bits in clock driver teardown
The clock driver used a heavy-handed approach where it turned off
all available clocks, while also possibly setting bits which are not
documented in the R-Car datasheet. Update the tables so that only
the bits which are documented are set or cleared when tearing down
the clock driver.
Note that the only clock left running before booting Linux are now
MFIC, INTC-AP, INTC-EX and SCIF2 / SCIF0 on V3x.
