Mattias Rönnblom 388c4c03ec power: handle frequency increase with turbo disabled 
Calling pstate's or acpi's rte_power_freq_up() when on the highest
non-turbo frequency results in an error, if turbo is enabled in the BIOS,
but disabled via the power library.
The error is in the form of a return code and a RTE_LOG() entry
on the ERR level.

According to the API documentation, the frequency is scaled up
"according to the available frequencies". In case turbo is disabled,
that frequency is not available. This patch's rte_power_freq_up()
behaviour is also consistent with how rte_power_freq_max() is
implemented (i.e. the highest non-turbo frequency is set, in case
turbo is disabled).

Fixes: 445c6528b5 ("power: common interface for guest and host")
Fixes: e6c6dc0f96 ("power: add p-state driver compatibility")
