intel_alm: direct LUTRAM cell instantiation
...
By instantiating the LUTRAM cell directly, we avoid a trip through
altsyncram, which speeds up Quartus synthesis time. This also gives
a little more flexibility, as Yosys can build RAMs out of individual
32x1 LUTRAM cells.
While working on this, I discovered that the mem_init0 parameter of
<family>_mlab_cell gets ignored by Quartus.
