[PATCH] ASoc: wm8731: fix wm8731_check_osc() connected condition

[Nicolas Ferre <nicolas.ferre@atmel.com>]

The crystal oscillator is only enabled if the WM8731_SYSCLK_XTAL master clock
is specified. Fix the connected() struct snd_soc_dapm_route function to take
this into account. Oscillator is not enabled on machine that need it otherwise.

Machine drivers have to make sure that they use the proper SYSCLK value.
