Remove gfx toggle. Hope thats all after the pie replaced it somewhat...
improve a calculation method for LTE antenna reception level

Current calculation uses a RSSNR value but it is unsuitable
for accurate reception level.
(The measurement requirement for RSSNR does not exist in 3GPP.)
Instead, it should use a RSRQ value defined by 3GPP
specification: TS 36.214.

The minimum level of RSRQ required to display Antenna icon
should be the minimum value of Qqualmin which is a minimum
required RSRQ defined by 3GPP specification: TS 36.331 RRC.

Also RSRP value thresholds is relatively high compared with
other mobile phone platforms, which make android seems
low sensitive to radio. This patch sets better thresholds.

PWM: disable HW overlays for PIE

SurfaceFlinger wont wake up the GPU in SysUI's fullscreen state,
probably because it does not occupy any tangible region. That sets poor
PIE into software rendering, which has bad effects on transparency and
mdp compositioning. Disabling HW overlays as long as PIE is active seems
like a good alternative for now.
