Srinivasan Shanmugam ccc514b7e7 drm/amd/display: Fix possible buffer overflow in 'find_dcfclk_for_voltage()'
when 'find_dcfclk_for_voltage()' function is looping over
VG_NUM_SOC_VOLTAGE_LEVELS (which is 8), but the size of the DcfClocks
array is VG_NUM_DCFCLK_DPM_LEVELS (which is 7).

When the loop variable i reaches 7, the function tries to access
clock_table->DcfClocks[7]. However, since the size of the DcfClocks
array is 7, the valid indices are 0 to 6. Index 7 is beyond the size of
the array, leading to a buffer overflow.

Reported by smatch & thus fixing the below:
drivers/gpu/drm/amd/amdgpu/../display/dc/clk_mgr/dcn301/vg_clk_mgr.c:550 find_dcfclk_for_voltage() error: buffer overflow 'clock_table->DcfClocks' 7 <= 7

Fixes: 3a83e4e64b ("drm/amd/display: Add dcn3.01 support to DC (v2)")
