ALSA: hda/tegra: use macro for codec probe

We have been using DT property "nvidia,max-codec-slot" to pass maximum
supported codec slots for the HDA controller. There is a fallback
option to use HDA_MAX_CODECS slots if the DT property is not specified.
Right now value passed from the DT and HDA_MAX_CODECS macro value are
same. Even in future if number of supported codec slots increases, the
macro in the driver can be updated. No need to have DT property for this.

This patch removes DT parsing of the property and instead uses the macro
HDA_MAX_CODECS to probe. Later DT entries can be removed.
