Yongbo Zhang 4875456b67 SoC: rsnd: add interrupt support for SSI BUSIF buffer 
[ Upstream commit 66c705d07d784fb6b4622c6e47b6acae357472db ]

SSI BUSIF buffer is possible to overflow or underflow, especially in a
hypervisor environment. If there is no interrupt support, it will eventually
lead to errors in pcm data.
This patch adds overflow and underflow interrupt support for SSI BUSIF buffer.
