Function and structure names in the Hyper-V DRM driver currently use "hyperv_" as the prefix. This conflicts with usage in core Hyper-V and VMBus code, and incorrectly implies that functions and structures in this driver apply generically to Hyper-V. A specific conflict arises for "hyperv_init", which is an initcall for generic Hyper-V initialization on arm64. The conflict prevents the use of initcall_blacklist on the kernel boot line to skip loading this driver. Fix this by substituting "hv_drm_" as the prefix for all functions and structures in this driver. In most places, this is replacing "hyperv_" with "hv_drm_". In a few places, the substitution results in "hv_drm_drm_", which has been collapsed to just "hv_drm_". In two cases, the existing prefix is a bare "hv" (including in the to_hv() macro), which has been replaced with "hv_drm" for consistency. The changes are all mechanical text substitution in symbol names. There are no other code or functional changes.
