Update ena-com for the ENAv2 version

The new ena-com is required for the ENAv2 release of the driver.

Genmask macro was fixed in the platform file.

The GENMASK macro is intended to work on 32-bit values. Before this
patch the, calling GENMASK(31, 0) would cause 32-bit value to be
shifted by 32. This could lead to unexpected behavior, as shifting by
the number greater or equal to word length is undefined operation.
