tizen: amlogic: Add hdmimode env variable

The hdmimode variable set to "1080p60hz" value allows the HDMI driver
to switch to default full HD timings for QHD/UHD monitors and such
monitors can still be used in lower resolution mode.
This a workaround until proper support for QHD/UHD is implemented
in the VPU driver.
The new variable is also used in kernel bootargs.
