tspp: Protect against buffer overflow

Change filter->priority to unsigned int. Since it was defined as integer,
it may have had negative value and cause accessing an array outside
of its region

msm: tspp: Request IRQs on first use

Reserving the IRQs on driver initialization is redundant and should
be done only when client first uses the driver. Also, it may prevent
transition to power saving modes.
Move IRQ requests to be done when first stream is opened, and free
when last stream is closed.

tspp: fix bam irq request preventing sleep

Registering and resetting BAM device upon initialization of tspp
driver requests bam irq resource, which prevents entering sleep.
Instead, BAM device is now initialized only when first needed which
is when the first channel is opened. BAM device is uninitialized
when channel is closed.
