drm/arm/malidp: use clk_bulk API in runtime PM resume and suspend
malidp_runtime_pm_resume() calls clk_prepare_enable() three times without checking the return value. If any clock fails to enable, the driver silently proceeds with unclocked hardware, leading to undefined behavior. Convert both the resume and suspend paths to use the clk_bulk API: clk_bulk_prepare_enable() in resume checks the return value and rolls back any successfully enabled clocks on failure; clk_bulk_disable_unprepare() in suspend keeps the two paths symmetric. This issue was found by code review without access to Mali DP hardware.
