By paving the CTRL reg value, the current code changes MIPI_CAL_PRESCALE
("Auto-cal calibration step prescale") from 1us to 0.1us (val=0). In the
description for PHY's noise filter (MIPI_CAL_NOISE_FLT), the TRM states
that if the value of the prescale is 0 (or 0.1us), the filter should be
set between 2-5. However, the current code sets it to 0.
For now, let's keep the prescale and filter values as-is, which is most
likely the power-on-reset values of 0x2 and 0xa, respectively.
