OMAP4: hwmod data: Add DMIC

Add HWMOD entries for the OMAP DMIC. The HWMOD entires define the system
resource requirements for the driver such as DMA addresses, channels,
and IRQ's. Placing this information in the HWMOD database allows for
more generic drivers to be written and having the specific implementation
details defined in HWMOD.

[b-cousson@ti.com: Change the wrong hwmod name,
add missing flag and re-order structures]
