drm/komeda: Fix bits parsing of GLB_CORE_ID

Browse source

GLB_CORE_ID contains the product and version information returned by the
hardware. The current macros parses VERSION_MINOR as a 4-bit field and
VERSION_STATUS as an 8-bit field, which does not match the register
layout. As a result, the driver reports an incorrect version number.

Fix the parsing macros to match the hardware specification:
- VERSION_MINOR is 8 bits at [11:4]
- VERSION_STATUS is 4 bits at [3:0]
