ASoC: amd: acp3x: Fix signedness bug in acp3x

In acp3x_audio_probe() platform_get_irq() may return error, but i2s_irq now
is unsigned int so the error handling is never triggered.

ASoC: amd: fix for pcm_read() error

Below phython script throwing pcm_read() error.

import subprocess

p = subprocess.Popen(["aplay -t raw -D plughw:1,0 /dev/zero"], shell=True)
subprocess.call(["arecord -Dhw:1,0 --dump-hw-params"], shell=True)
subprocess.call(["arecord -Dhw:1,0 -fdat -d1 /dev/null"], shell=True)
p.kill()

Handling ACP global external interrupt enable register
causing this issue.
This register got updated wrongly when there is active
stream causing interrupts disabled for active stream.
Refactored code to handle enabling and disabling external interrupts.

ASoC: AMD: Clear format bits before setting them

This avoids residual bit form previous format when the format is changed.
Hence, the resultant format is not an invalid one.

ASoC: amd: Added ACP3x system resume and runtime pm

When system wide suspend happens, ACP will be powered off
and when system resumes,for audio usecase to continue,all
the runtime configuration data needs to be programmed again.
Added resume pm call back to ACP pm ops and also added runtime
PM operations for ACP3x PCM platform device.
Device will enter into D3 state when there is no activity
on audio I2S lines.
