media: tegra-video: Compute settle times based on the clock rate

Browse source 
Settle time determines the number of cil clock cyles to wait after
LP00 when moving from LP to HS.

This patch computes T-CLK-SETTLE and T-HS-SETTLE times based on cil
clock rate and pixel rate from the sensor and programs them during
streaming.

T-CLK-SETTLE time is the interval during which receiver will ignore
any HS transitions on clock lane starting from the beginning of
T-CLK-PREPARE.

T-HS-SETTLE time is the interval during which recevier will ignore
any HS transitions on data lane starting from the beginning of
T-HS-PREPARE.
