ASoC: cs-amp-lib: Return attributes from cs_amp_get_efi_variable()

Add a pointer argument to cs_amp_get_efi_variable() to optionally
return the EFI variable attributes.

Originally this function internally consumed the attributes from
efi.get_variable(). The calling code did not use the attributes
so this was a small simplification.

However, when writing to a pre-existing variable we would want to
pass the existing attributes to efi.set_variable(). This patch
deals with the change to return the attribute in preparation for
adding code to update the variable.
