drm_hwcomposer: use CamelCase in source/header files related to class
Main goal is to increase readability of file names. AOSP uses camelcase for files in many projects. Lets do the same for drm_hwcomposer. Keep platform/ directory as is, since class names is different from file names. Signed-off-by: Roman Stratiienko <r.stratiienko@gmail.com> Change-Id: I7e992357851c2a86711f4da1241c4d507359e56b
