drm/via: drop use of DRM(READ|WRITE) macros

The DRM_READ, DRM_WRITE macros comes from the deprecated drm_os_linux.h
header file. Remove their use to remove this dependency.

Replace the use of the macros with static inline variants.

v4:
- Use a more standard via_write8_mask() function (Emil)

v3:
- Use static inline functions, rather than macros (Emil)
- Use dedicated mask variants for byte access (Emil)
