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.
