[ Upstream commit 6205406cf6f282d622f31de25036e6d1ab3a2ff5 ]

Init field must be cleared in driver probe as this structure is not
dinamically allocated. If not, wrong flags can be passed to core.

The ARC SDP I2S clock can be programmed using a
specific PLL.

This patch has the goal of adding a clock driver
that programs this PLL.

At this moment the rate values are hardcoded in
a table but in the future it would be ideal to
use a function which determines the PLL values
given the desired rate.
