drm/amd/pp: Print out voltage/clock range in sysfs
when user cat pp_od_clk_voltage
add display info about the sclk/mclk/vddc range that user can overdrive
output as:
OD_SCLK:
0: 300MHz 900mV
1: 400MHz 912mV
2: 500MHz 925mV
3: 600MHz 937mV
4: 700MHz 950mV
5: 800MHz 975mV
6: 900MHz 987mV
7: 1000MHz 1000mV
OD_MCLK:
0: 300MHz 900mV
1: 1500MHz 912mV
OD_RANGE:
SCLK: 300MHz 1200MHz
MCLK: 300MHz 1500MHz
VDDC: 700mV 1200mV
also
1. remove unnecessary whitespace before a quoted newline
2. change unit of frequency Mhz to MHz
