is_sys_clk_from_pll() is used as a snd_soc_dapm_route.connected callback, checking RT5651_GBL_CLK to determine if the sys-clk is PLL1 and thus the PWR_PLL bit in reg PWR_ANLG2 must be set. RT5651_GBL_CLK is changed by rt5651_set_dai_sysclk(), which gets called by the pre_pmu / post_pmd functions of the "Platform Clock" dapm-supply. This creates an ordering issue, during a dapm transition first all connected() callbacks are called to build a list of supplies to enable and then the complete list is walked to enable the supplies. Since the connected() check happens before enabling any supplies, is_sys_clk_from_pll() ends up deciding if the PWR_PLL bit should be set based on the state the "Platform Clock" supply had *before* the transition. This sometimes results in PWR_PLL being off, even though *after* the transition PLL1 is configured as sys-clk. This commit removes is_sys_clk_from_pll() instead simply setting / clearing PWR_PLL in rt5651_set_dai_sysclk() based on the selected sys-clk, which fixes this and as a bonus results in a nice cleanup.
