of which is unnecessary in C language semantics.

(v1)
- implement emit_clk_levels for vega10, based on print_clk_levels,
but using sysfs_emit rather than sprintf
- modify local int vars to use uint32_t to match arg type of
called functions
- add return of error codes
- refactor OD_XXX cases to return early with -EOPNOTSUPP if
!(hwmgr->od_enabled)

In file vega10_hwmgr.c, the names of struct vega10_power_state *
and struct pp_power_state * are confusingly used, which may lead
to some confusion.
Status quo is that variables of type struct vega10_power_state *
are named "vega10_ps", "ps", "vega10_power_state". A more
appropriate usage is that struct are named "ps" is used for
variabled of type struct pp_power_state *.
So rename struct vega10_power_state * which are named "ps" and
"vega10_power_state" to "vega10_ps", I also renamed "psa" to
"vega10_psa" and "psb" to "vega10_psb" to make it more clearly.
The rows longer than 100 columns are involved.

1. Only the high dpm level speed/width can be overrided
if the requested values are out of the pcie capability.
