ipa: rkisp1: blc: Add support for BLS in compand

Extend the RkISP1 BLC algorithm to use the ISP 'companding' block for
versions of the ISP (such as the one on the i.MX8MP) that lack the
dedicated BLS block but implement BLS as part of the companding block.

As access to the companding block requires the extensible parameters
format, disable BLC when using the legacy parameters format on i.MX8MP
to avoid crashes at runtime with older kernels.
