[ Upstream commit 2b21207afd06714986a3d22442ed4860ba4f9ced ]
As the pll_id and pll_id can be zero (WM8960_SYSCLK_AUTO) with the commit 2bbc2df46e67 ("ASoC: wm8960: Make automatic the default clocking mode")
Then the machine driver will skip to call set_sysclk() and set_pll() for codec, when the sysclk rate is different with what wm8960 read at probe, the output sound frequency is wrong.
So change the fll_id and pll_id initial value, still keep machine driver's behavior same as before.
