Fix PPT - reset calls, unit format, and get_power_cap()

Browse Source 
Changes:
  - Simplified reset calls
  - Updated static limit N/A values to all possible data
  (helps csv format be consistent)
  - Unit format was broken on static
  - get_power_cap() had min/max values swapped, and the return
    was missing two fields
  - Updated changelog to reflect all changes

- **Added support for PPT1 power limit information**.
- Support has been added for querying and setting the PPT (Package Power Tracking) limits
- There are two PPT limits, PPT0 has lower limit and tracks a filtered version of the input power and PPT1 has higher limit but tracks the raw input power. This is to catch spikes in the raw data.
- New API added:
- amdsmi_get_supported_power_cap(): Returns which power cap types are supported on the device (PPT0, PPT1). This will allow users to know which power cap types they can get/set.
- Original APIs remain the same but now can get/set both PPT0 and PPT1 limits (on supported hardware):
- amdsmi_get_power_cap_info()
- amdsmi_set_power_cap()
- See the Changed section for changes made to the `set` and `static` commands regarding support for PPT1.
### Changed
- **`amd-smi set --power-cap` now requires sepcification of the power cap type**.
- command now takes the form: `amd-smi set --power-cap <power-cap-type> <new-cap>`
- acceptable power cap types are "ppt0" and "ppt1"
- **`amd-smi set --power-cap` now requires specification of the power cap type**.
- Command now takes the form: `amd-smi set --power-cap <power-cap-type> <new-cap>`. Acceptable power cap types are "ppt0" and "ppt1".
Ex.
```console
$ sudo amd-smi set --power-cap ppt1 1150
GPU: 0
POWERCAP: Successfully set ppt1 power cap to 1150W
...
```
```console
$ sudo amd-smi set --power-cap ppt1 1150
GPU: 0
POWERCAP: Successfully set PPT1 power cap to 1150W
...
```
- **`amd-smi reset --power-cap` will attempt to reset both power caps**.
- When using the reset command, both PPT0 and PPT1 power caps will be reset to their default values. If a device only has PPT0, then only PPT0 will be reset.
Ex.
```console
$ sudo amd-smi reset --power-cap ppt1 1150
GPU: 0
POWERCAP:
PPT0: Successfully reset power cap to 203W
PPT1: [AMDSMI_STATUS_NOT_SUPPORTED] Unable to reset to default power cap
...
```
- **`amd-smi static --limit` now has a PPT1 section when PPT1 is available**.
```console
$ amd-smi static --limit
GPU: 0
LIMIT:
PPT0:
MAX_POWER_LIMIT: 1000
MIN_POWER_LIMIT: 0
SOCKET_POWER_LIMIT: 1000
PPT1:
MAX_POWER_LIMIT: 1300
MIN_POWER_LIMIT: 1100
SOCKET_POWER_LIMIT: 1250
SLOWDOWN_EDGE_TEMPERATURE: N/A
...
```
- The static --limit command has been updated to include PPT1 power limit information when available on the device.
```console
$ amd-smi static --limit
GPU: 0
LIMIT:
PPT0:
MAX_POWER_LIMIT: 1000
MIN_POWER_LIMIT: 0
SOCKET_POWER_LIMIT: 1000
PPT1:
MAX_POWER_LIMIT: 1300
MIN_POWER_LIMIT: 1100
SOCKET_POWER_LIMIT: 1250
SLOWDOWN_EDGE_TEMPERATURE: N/A
...
```
- JSON and CSV formats are updated to reflect this change as well.
Ex.
```console
$ amd-smi static --limit --json

"gpu_data": [
{
"gpu": 0,

"ppt0": {
