Subject: [PATCH] sm6375-common: powerhint: Set screen-off schedutil ratelimits

Use a more power-friendly rate limit configuration (2ms up/down)
to reduce power consumption a bit when the screen is off.

Power results during screen off GPS usage, measured by
Alex Naidis <alex.naidis@paranoidandroid.co> on SDM845:

Before:
392mW
93.5mA

After:
378.5mW
90.2mA
