drm/i915: Add parsing support for new MIPI blocks in VBT
The parser extracts the config block(#52) and sequence(#53) data and store in private data structures. v2: Address review comments by Jani - adjust code for the structure changes for bdb_mipi_config - add boundry and buffer overflow checks as suggested - use kmemdup instead of kmalloc and memcpy v3: More strict check while parsing VBT - Ensure that at anytime we do not go beyond sequence block while parsing - On unknown element fail the whole parsing v4: Style changes and spell check mostly as suggested by Jani Signed-off-by: Shobhit Kumar <shobhit.kumar@intel.com> Reviewed-by: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
