msm: kgsl: Pass chipid in correct format to gmufw for A660 variant

GMU firmware to differentiate between A660 and A660 GPU variant
expects target version in bit 28-31. In device tree, target
version is specified in upper nibble of patch to align with
usermode driver expectation.

This change correctly formats the chipid before passing it to GMU
firmware to avoid boot-up issues.
