Add logic in order to be able to turn on the control buffer on MT8365.
This change now allows to have control buffer support for MTK_THERMAL_V1,
and it allows to define the register offset, and mask used to enable it.

This is effectively GENMASK(31, 6) | BIT(3) :-)

...and this is BIT(0)

Thank you for the catch, will update them appropriately.

Since you're practically restructuring this function, please fix this wrong
variable type, as this should be a u32.

Sure agreed.


Thank you Angelo for the review.
