The V4L2_CID_ISO_SENSITIVITY control menu values should be
standard ISO values multiplied by 1000. Multiply all menu
items by 1000 so ISO is properly reported as 50...3200 range.
This applies to kernels 3.5+.

Add control for locking automatic exposure, focus and white balance
adjustments. While at it, tidy up the data structure documentation.

This patch adds V4L2_CID_EXPOSURE_METERING control which allows
to select the light metering mode for automatic exposure as one
of the following modes: spot (small area at the frame center),
center weighted and frame averaged.

Add integer menu control for exposure bias. The control value range is
-2.0 EV to +2.0 EV, in 0.5 EV steps.

Replace the V4L2_CID_AUTO_WHITE_BALANCE control with its extended
version - V4L2_CID_AUTO_N_PRESET_WHITE_BALANCE so the white balance
presets feature is exposed to user land.

The parameters corresponding to the V4L controls can be reconfigured
only in associated M-5MOLS operation mode. Use struct v4l2_ctrl
priv field to assign the working mode to the controls which can be
modified only in certain conditions.

This patch is a prerequisite for the new controls addition. It consolidates
the control handling code, which is moved to m5mols_controls.c and
staticized. The controls initialization is reordered to better reflect
the control clusters and make the diffs smaller when new controls are added.
To make the code easier to follow when more controls is added use separate
set function for each control.
Rewrite the image effect registers handling.

For now, the m5mols_read() share in case of I2C packet 1, 2, 4 byte(s) width.
So, this commit adds 3 functions - m5mols_read_u8/u16/u32() according to byte
width of I2C packet. And, the u32 variables in spite of u8 or u16 for fitting
to m5mols_read() having no choice, is replaced to have original byte width
like u8, u16, u32 as same reason.
