mb/intel/adlrvp: Set half_populated true for ADL-N

Alder Lake N has single memory controller with 64-bit bus width. Alder
Lake common meminit block driver considers bus width to be 128-bit and
populates the meminit data accordingly. By setting half_populated to
true, only the bottom half is populated.

Ideally, half_populated is used in platforms with multiple channels to
enable only one half of the channel. Alder Lake N has single channel,
and it would require for new structures to be defined in meminit block
driver for LPx memory configurations. In order to avoid adding new
structures, set half_populated to true. This has the same effect as
having single channel with 64-bit width.
