drm/msm/registers: Fix encoding fields in 64b registers

Based on mesa commit 3f70b0578402 ("freedreno/registers: Fix encoding
fields in 64b registers"), but with some fixes to not skip emitting
interrupt enum values.

v2: Don't append "ull" to 32b reg MASK defines, to avoid printf format
    conversion warnings all over the place
