ASoC: amd: fix for pcm_read() error

[ Upstream commit 6879e8e759bf9e05eaee85e32ca1a936e6b46da1 ]

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.
