Hello Julius Werner,

mb/google/herobrine: Mask out upper bits from sku_id()

When retrieving the SKU id value through the sku_id() function in
mainboard_needs_pcie_init(), we only want the values in the lower 5
bits as we can only represent SKU id up to 27.  Everything in the
higher bits should be masked out because they are not needed.

BUG=b:254281839
BRANCH=None
TEST=Make sure that NVMe is not initialized
     Tested on a herobrine board with SKU id 0
