drm/aspeed: Balance the display clock enable on teardown
aspeed_gfx_load() enables the display clock without checking the return
value and never disables it on probe failure or removal. devm_clk_get()
only releases the clock reference, leaving the enable unbalanced.
Use devm_clk_get_enabled() to handle enable failures and automatically
disable and unprepare the clock on probe failure or removal.
This issue was identified during our ongoing static-analysis research
while reviewing kernel code.
