disp: msm: format register/debugbus dumping in logs
Add macros for logging the registers/debugbus, so all blocks can use the same macros to keep the log format consistent. Change-Id: Ie28ce83a742f24f3091bedab66c8cf1454bbb943 Signed-off-by: Andhavarapu Karthik <kartkart@codeaurora.org> Signed-off-by: Veera Sundaram Sankaran <veeras@codeaurora.org>
