meteorlake: Rename `SOC_INTEL_METEORLAKE_U_P` as per latest EDS

This patch renames config `SOC_INTEL_METEORLAKE_U_P` to
`SOC_INTEL_METEORLAKE_U_H` as per Intel Meteor Lake Processor EDS
version 1.3.1 (doc number: 640228).

With new branding, the MTL-U/H-Processor Line offered in a 1-chip platform that includes the Compute, SOC, GT, and IOE tile on the
same package.
