soc: mediatek: mt8365-mmsys: Fix routing table masks and values

The mmsys driver reads the routing table and writes to the
hardware `val & mask`, but multiple entries in the mmsys
routing table for the MT8365 SoC are setting a 0x0 mask:
this effectively writes .. nothing .. to the hardware.

That would never work, and if the display controller was
actually working with the mmsys doing no routing at all,
that was only because the bootloader was correctly setting
the display controller routing registers before booting the
kernel, and the mmsys was never reset.

Make this table to actually set the routing by adding the
correct register masks to it.

While at it, also change MOUT val definitions to BIT(x), as
the MOUT registers are effectively checking for each bit to
enable output to the corresponding HW.
Please note that, for this SoC, only the MOUT registers are
checking bits (as those can enable multiple outputs), while
the others are purely reading a number to select an input.
