freedreno/fdl: Add base_align

Browse Source 
Tell users what the base address of the image needs to be aligned to.
These values are based on experimentation via passing an offset to
vkBindImageMemory with turnip and seeing if tests still pass. Note that
r8g8 is also special in this regard, however it actually has an
increased alignment (in bytes).
