Define the most frequently used bitmasks of the Interrupt Enable /
Interrupt Status register with consistent naming ( with _EN suffix).
Use meaningful concatenation of bitfields for INT_EN_MASK, which shows
which interrupts are enabled by default.
No functional changes.

v1->v2:
Balaji's comments to not set ERR_EN for INT_EN_MASK is now
handled.
