ec/google/chromeec: Introduce SKU_ID helpers
The following introduces helpers that, by default, accommodate a larger SKU id space. The following is the rational for that: Allow INT32_MAX SKU id encodings beyond UINT8_MAX. This allows for the SKU id to accommodate up to 4 bytes however we reserve the highest bit for SKU_UNKNOWN to be encoded. However, the legacy UINT8_MAX encoding is supported by leveraging the Kconfig by overriding it with the legacy max of 0xff. Follow ups migrate boards to this common framework. V.2: Fixup array size && drop sku_id SKU_UNKNOWN check and pass whatever is set to userspace as firmware doesn't care about the value. V.3: Use SPDX-License header.
