i.MX25: add AUDMUX and SSI support
* add clocks for audmux and ssi 1 & 2 * add irq for ssi 1 & 2 * add devices platform for ssi1 & 2 * update audmux-v2 for i.MX25 * add base addresses for audmux & ssi 1 & 2 * add iomux configuration for GPIO for AUD5 port Signed-off-by: Eric Bénard <eric@eukrea.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
