Paul Elder ac79beb913 media: rkisp1: Add support for the companding block 
Add support to the rkisp1 driver for the companding block that exists on
the i.MX8MP version of the ISP. This requires usage of the new
extensible parameters format, and showcases how the format allows for
extensions without breaking backward compatibility.

/**
* struct rkisp1_ext_params_block_header - RkISP1 extensible parameters block
* header
*
* This structure represents the common part of all the ISP configuration
* blocks. Each parameters block shall embed an instance of this structure type
* as its first member, followed by the block-specific configuration data. The
* driver inspects this common header to discern the block type and its size and
* properly handle the block content by casting it to the correct block-specific
* type.
*
* The @type field is one of the values enumerated by
* :c:type:`rkisp1_ext_params_block_type` and specifies how the data should be
* interpreted by the driver. The @size field specifies the size of the
* parameters block and is used by the driver for validation purposes.
*
* The @flags field is a bitmask of per-block flags RKISP1_EXT_PARAMS_FL_*.
*
* When userspace wants to configure and enable an ISP block it shall fully
* populate the block configuration and set the
* RKISP1_EXT_PARAMS_FL_BLOCK_ENABLE bit in the @flags field.
*
* When userspace simply wants to disable an ISP block the
* RKISP1_EXT_PARAMS_FL_BLOCK_DISABLE bit should be set in @flags field. The
* driver ignores the rest of the block configuration structure in this case.
*
* If a new configuration of an ISP block has to be applied userspace shall
* fully populate the ISP block configuration and omit setting the
* RKISP1_EXT_PARAMS_FL_BLOCK_ENABLE and RKISP1_EXT_PARAMS_FL_BLOCK_DISABLE bits
* in the @flags field.
*
* Setting both the RKISP1_EXT_PARAMS_FL_BLOCK_ENABLE and
* RKISP1_EXT_PARAMS_FL_BLOCK_DISABLE bits in the @flags field is not allowed
* and not accepted by the driver.
*
* Userspace is responsible for correctly populating the parameters block header
* fields (@type, @flags and @size) and the block-specific parameters.
*
* For example:
*
* .. code-block:: c
*
* void populate_bls(struct rkisp1_ext_params_block_header *block) {
* struct rkisp1_ext_params_bls_config *bls =
* (struct rkisp1_ext_params_bls_config *)block;

/**
* struct rkisp1_ext_params_cfg - RkISP1 extensible parameters configuration
*
* This struct contains the configuration parameters of the RkISP1 ISP
* algorithms, serialized by userspace into a data buffer. Each configuration
* parameter block is represented by a block-specific structure which contains a
* :c:type:`rkisp1_ext_params_block_header` entry as first member. Userspace
* populates the @data buffer with configuration parameters for the blocks that
* it intends to configure. As a consequence, the data buffer effective size
* changes according to the number of ISP blocks that userspace intends to
* configure and is set by userspace in the @data_size field.
*
* The parameters buffer is versioned by the @version field to allow modifying
* and extending its definition. Userspace shall populate the @version field to
* inform the driver about the version it intends to use. The driver will parse
* and handle the @data buffer according to the data layout specific to the
* indicated version and return an error if the desired version is not
* supported.
*
* Currently the single RKISP1_EXT_PARAM_BUFFER_V1 version is supported.
* When a new format version will be added, a mechanism for userspace to query
* the supported format versions will be implemented in the form of a read-only
* V4L2 control. If such control is not available, userspace should assume only
* RKISP1_EXT_PARAM_BUFFER_V1 is supported by the driver.
*
* For each ISP block that userspace wants to configure, a block-specific
* structure is appended to the @data buffer, one after the other without gaps
* in between nor overlaps. Userspace shall populate the @data_size field with
* the effective size, in bytes, of the @data buffer.
*
* The expected memory layout of the parameters buffer is::
