drivers: gpu: Include appropriate header file in si_smc.c and remove prototype declaration from header file sislands_smc.h

Include header file gpu/drm/radeon/sislands_smc.h in drm/radeon/si_smc.c
because it uses function declared in the header file.

Remove prototype declaration of function si_set_smc_sram_address() from
drm/radeon/sislands_smc.h because the function is used only in one file
where it is declared static already.

This eliminates the following warnings in drm/radeon/si_smc.c:

smc registers are access indirectly via the main mmio aperture, so
there may be problems with concurrent access.  This adds a spinlock
to protect access to this register space.

This adds dpm support for SI asics.  This includes:
- dynamic engine clock scaling
- dynamic memory clock scaling
- dynamic voltage scaling
- dynamic pcie gen1/gen2/gen3 switching
- power containment
- shader power scaling

Set radeon.dpm=1 to enable.

v2: enable hainan support, rebase
v3: guard acpi stuff
v4: fix 64 bit math
v5: fix 64 bit div harder
