There is no anymore legacy driver for OMAP24XX Enhanced Audio Controller
in linux-omap and it was newer in mainline so cleanup these unneeded
defines and initialization code.

Fix the possible race condition in omap_free_dma(). Function omap_free_dma()
sets the dev_id = -1 and then accesses the channel afterwards to clear it.
But setting the dev_id=-1 makes the channel available for allocation again.
So it is possible someone else can grab it and results are unpredictable.
To avod this DMA channle is cleared first and then the dev_id = -1 is set.
Thanks to McNeil, Sean <sean.mcneil@ti.com> for ointing out this issue.

The VIC code will attempt to perform som
default set_irq_chip() and set_irq_chip_data()
on all IRQs supported by the VIC, while the new
IRQ handling code strictly checks for the global
NR_IRQS to be respected also for these IRQs.
This patch will respect the interrupt mask passed
to the VIC driver and will prevent it from
attempting to call these functions on any unused
interrupts.

When unmapping N pages (e.g. shared memory) the amount of TLB flushes
done can be (N*PAGE_SIZE/ZAP_BLOCK_SIZE)*N although it should be N at
maximum. With PREEMPT kernel ZAP_BLOCK_SIZE is 8 pages, so there is a
noticeable performance penalty when unmapping a large VMA and the system
is spending its time in flush_tlb_range().
The problem is that tlb_end_vma() is always flushing the full VMA
range. The subrange that needs to be flushed can be calculated by
tlb_remove_tlb_entry(). This approach was suggested by Hugh Dickins,
and is also used by other arches.
The speed increase is roughly 3x for 8M mappings and for larger mappings
even more.
