Wyatt Wood 1db1469592 drm/amd/display: Fix ABM memory alignment issue 
[Why]
Due to packing of abm_config_table, memory addresses aren't aligned to
32 bit boundary dmcub prefers.  Therefore when using pointers to this
structure, it's possible that dmcub will automatically align the data
read from that address, yielding incorrect values.

[How]
Instead of packing 1 byte boundary, explicitly pack values to 4 byte
boundary. Since there is a dependency on the existing iram table
structure on driver side, we must copy to a second structure, which is
aligned correctly, before passing to fw.
