clk: mediatek: relicense mt7986 clock driver to GPL-2.0 The previous mt7986 clock drivers were incorrectly marked as GPL-1.0. This patch changes the driver to the standard GPL-2.0 license.

clk: Explicitly include correct DT includes The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

clk: mediatek: Remove CLK_SET_PARENT from all MSDC core clocks Various MSDC core clocks, used for multiple MSDC controller instances, share the same parent(s): in order to add parents selection in the mtk-sd driver to achieve an accurate clock rate for all modes, remove the CLK_SET_RATE_PARENT flag from all MSDC clocks for all SoCs: this will make sure that a clk_set_rate() call performed for a clock on a secondary controller will not change the rate of a common parent, which would result in an overclock or underclock of one of the controllers.
