The documentation states that the BNR factor is a multiplier coded as
u3.13 and with a range of (0, 8). This is not correct, as the isp is
adding 1.0 to the gain applied, ie Pout = { Pin * (1 + Gx) }.
It means that a gain of 1.0 should be coded as 0.

The ISP8000Nano v18.02 (found in the i.MX8MP) requires the ISP to be
enabled (as indicated by the ISP_CTRL.ISP_ENABLE bit) to configure the
lens shading table in internal RAM. The driver currently configures all
ISP initial parameters before enabling the ISP, which causes the LSC RAM
to not be initialized properly.
To fix this, split the rkisp1_params_configure() function into a
rkisp1_params_pre_configure() and a rkisp1_params_post_configure(). The
former configures all ISP parameters but LSC, while the latter
configures LSC. To implement this, the rkisp1_params_apply_params_cfg()
function is deconstructed, with two small helpers created to deal with
the parameters buffers, which are then used in rkisp1_params_isr(),
rkisp1_params_pre_configure() and rkisp1_params_post_configure().
While this initialization ordering is only needed for the ISP8000Nano
v18.02, it doesn't affect other ISP versions negatively, and can thus be
followed unconditionally.

the floating point values to the nearest Q1.7 fixed-point value,
adjusting the rounding to ensure that the sum of each line in the matrix
is preserved to avoid overflows.

other color space fields:
- The ycbcr_enc field will be used to configure the RGB to YUV matrix
(currently hardcoded to Rec. 601).
- The colorspace (which controls the color primaries) and xfer_func
fields will not be used to configure the ISP, as the corresponding
hardware blocks (the cross-talk RGB to RGB matrix and the tone mapping
curve) are programmed directly by applications through ISP parameters.
Nonetheless, those two fields should be set by applications to match
the ISP configuration, in order to propagate the correct color space
