The post-divider has a default register value of 2, i.e. a divider of 3. This means the clock rate fed to the audio codec would be off. This was discovered when porting sigma-delta modulation for the PLL to sun5i, which needs the post-divider to be 1. Fix the bit offset, so we do actually force the post-divider to a certain value.

This was a problem when the irq is described as a GpioInt rather then an Interrupt in the DSDT as for GpioInt-s the value passed to request_irq is honored. This commit fixes this by requesting the correct trigger type depending on bcm_device.irq_polarity. 2) bcm_device.irq_polarity was used to directly store an ACPI polarity value (ACPI_ACTIVE_*). This is undesirable because hci_bcm is also used with device-tree and checking for something like ACPI_ACTIVE_LOW in a non ACPI specific function like bcm_request_irq feels wrong. This commit fixes this by renaming irq_polarity to irq_active_low and changing its type to a bool.

The macro also does not return the proper level value to use. This fixes this by preserving all bits from the register that are not the level while setting the level.
