[PATCH 69/85] drivers: gpu: Move prototype declarations to header file si_dpm.h

[Rashika Kheria]

Move prototype declarations of functions
si_get_ddr3_mclk_frequency_ratio(), si_get_mclk_frequency_ratio()
and si_trim_voltage_table_to_fit_state_table() to header file
drm/radeon/si_dpm.h because they are used by more than one file.

This eliminates the following warnings from drm/radeon/si_dpm.c:
drivers/gpu/drm/radeon/si_dpm.c:3698:4: warning: no previous prototype for 
?si_get_ddr3_mclk_frequency_ratio? [-Wmissing-prototypes]
drivers/gpu/drm/radeon/si_dpm.c:3711:4: warning: no previous prototype for 
?si_get_mclk_frequency_ratio? [-Wmissing-prototypes]
drivers/gpu/drm/radeon/si_dpm.c:3793:6: warning: no previous prototype for 
?si_trim_voltage_table_to_fit_state_table? [-Wmissing-prototypes]
