clk: renesas: Do not enable MSTP4 extra modules on R8A77995 D3
Since commit a2bd99549c61 ("clk: renesas: Tear clock controller down
last before booting OS") enabling the module gated by bit 8 in MSTP4
prevents Linux from booting. The bits 8 and 7 of MSTP4 where only
documented in early versions of the datasheet and have since been
removed.
To allow Linux to boot update the MSTP4 enable value to reflect the
hardware default, 0x80.
