Subject: [PATCH] drm/vc4: hvs: Use pointer to HVS in HVS_READ and
 HVS_WRITE macros

Those macros are really about the HVS itself, and thus its associated
structure vc4_hvs, rather than the entire (virtual) vc4 device.

Let's change those macros to use the hvs pointer directly, and change
the calling sites accordingly.
