drm/ast: Handle known struct ast_dramstruct with helpers
Most of struct ast_dramstruct stores hardware state. Some index
values have known or special meaning. The known values are
- 0xffff - Terminal entry in the array
- 0xff00 - Delays the programming for usecs
- 0x0004 - Sets the type of DRAM
Add constants and helper macros for these cases. Also add a helper
macro for testing. Update Gen1 and Gen2+ accordingly.
