[PATCH 3/3] clk: imx: imx8qxp-lpcg: Return an error if the parent names cannot be read

[Abel Vesa]

When of_clk_parent_fill() does not fill in a parent name for every
clock, imx_lpcg_parse_clks_from_dt() returns the number of clocks
instead of an error code. The probe then falls back to the legacy
binding as it does on any error, but a positive value is not what the
function is meant to return on failure.

Return -EINVAL instead, like the other parsing errors do.
