mb/google/poppy/variants/nami: change type of board_sku_id() to uint32_t
Tools/scripts, like mosys/arc-setup, use int(4 bytes) to
read the sku id. In order to support "-1", we need to use
uint32_t(4 bytes) instead of using uint16_t(2 bytes) data type.
Otherwise, tools/scripts will read 65535 instead of -1.
Another reason to change this is that sku_id can be
supported by ec up to 4 bytes.
BUG=b:73792190
TEST=mosys output "Platform not Supported" for -1 sku id
arc-setup read -1 sku id
