Since user may need to check the current configuration of the
interrupt coalesce, so add debugfs support for query this info,
which includes DIM profile, coalesce configuration of both software
and hardware.

For device whose version is above V3(include V3), the GL can
select EQ or CQ mode, so adds support for it.
In CQ mode, the coalesced timer will restart upon new completion,
while in EQ mode, the timer will not restart.

QL(quantity limiting) means that hardware supports the interrupt
coalesce based on the frame quantity. QL can be configured when
int_ql_max in device's specification is non-zero, so add support
to configure it. Also, rename two coalesce init function to fit
their purpose.

#8 adds a check for the read-only private flag.
#9 & #10 adds support for EQ/CQ configuration, and adds a control
private flag in ethtool.
