Add description for values written into registers QINT_XXXX
and small cosmetic changes for MSI/LEGACY interrupts
configuration in the same way as for MSI-X.
Descriptions confirm the code is written correctly and
make the code clear. Small cosmetic changes for MSI/LEGACY
interrupts make code clear in the same manner as for MSI-X
interrupts.
