Codec reset gpio configuration needs to be updated
before slimbus master component is initialized otherwise
codec cannot be enumerated on the bus. Add a new platform
device driver to update the codec reset gpio configuration
to valid state (output, drive-strength) before slimbus

When SLIMBUS data channel is to be torn down, CODEC driver
waits for channel removal interrupt from SLIMBUS slave device
with 1 second timeout as measure to prevent system from lock
down in case channel removal interrupt never arrive due to
known reason. When ADSP SSR happen, SLIMBUS would be reset
hence data channel will be gone inherently. Waiting for 1
second will only prolong SSR recovery latency. Update to
avoid the delay after SSR.
