Subject: [PATCH 2/3] media: mali-c55: Remove duplicated version check

The Mali C55 driver uses the v4l2-isp framework, which performs
validation of the parameters buffer versioning in the
v4l2_isp_params_validate_buffer() function.

It is not necessary to replicate the validation of the parameters buffer
versioning in the platform-specific implementation.

Remove it.
