    drm/i915: Convert REG_GENMASK* to fixed-width GENMASK_*
    
    Now that include/linux/bits.h implements fixed-width GENMASK_*, use them
    to implement the i915/xe specific macros. Converting each driver to use
    the generic macros are left for later, when/if other driver-specific
    macros are also generalized.
