clk: qcom: clk-alpha-pll: drop lucid-evo pll enabled warning

The boot firmware may have left the display enabled and its PLL running,
which currently generates a warning on boot (e.g. on x1e80100):

	disp_cc_pll0 PLL is already enabled

Drop the bogus warning and fix up the PLL enabled error handling
(trion_pll_is_enabled() only returns 0 or 1).
