drm/amd/display: fix incompatible structure layouts

Building the amd display driver with link-time optimizations revealed a bug
that caused dal_cmd_tbl_helper_dce80_get_table() and
dal_cmd_tbl_helper_dce110_get_table() get called with an incompatible
return type between the two callers in command_table_helper.c and
command_table_helper2.c:

drivers/gpu/drm/amd/amdgpu/../display/dc/bios/dce80/command_table_helper_dce80.h:31: error: type of 'dal_cmd_tbl_helper_dce80_get_table' does not match original declaration [-Werror=lto-type-mismatch]
 const struct command_table_helper *dal_cmd_tbl_helper_dce80_get_table(void);

drivers/gpu/drm/amd/amdgpu/../display/dc/bios/dce80/command_table_helper_dce80.c:351: note: 'dal_cmd_tbl_helper_dce80_get_table' was previously declared here
 const struct command_table_helper *dal_cmd_tbl_helper_dce80_get_table(void)

drivers/gpu/drm/amd/amdgpu/../display/dc/bios/dce110/command_table_helper_dce110.h:32: error: type of 'dal_cmd_tbl_helper_dce110_get_table' does not match original declaration [-Werror=lto-type-mismatch]
 const struct command_table_helper *dal_cmd_tbl_helper_dce110_get_table(void);

drivers/gpu/drm/amd/amdgpu/../display/dc/bios/dce110/command_table_helper_dce110.c:361: note: 'dal_cmd_tbl_helper_dce110_get_table' was previously declared here
 const struct command_table_helper *dal_cmd_tbl_helper_dce110_get_table(void)

The two versions of the structure are obviously derived from the same
one, but have diverged over time, before they got added to the kernel.

This moves the structure to a new shared header file and uses the superset
of the members, to ensure the interfaces are all compatible.
