clk: zte: set CLK_SET_RATE_PARENT for a few zx296718 clocks To support VOU VGA display driver with different modes, we need to set flag for a few clocks, so that clk_set_rate() call in VOU driver can get VGA device desired pixel rate. While at it, the divider between pll_vga and clk_vga gets corrected, as it's 1:1 instead of 1:2.

clk: zx296718: register driver earlier with core_initcall Clock driver should be registered with an earlier initcall than module_init which is used by most of client device drivers. Otherwise, probing of these client drivers will likely be deferred due to that calls into clk API will return -EPROBE_DEFER. Deferred probing is not a problem for most subsystems, but could bring some side effect for particular subsystem, like display. On ZX296718 platform, we get Linux logo and boot log lost from display device, just because the DRM/KMS driver gets -EPROBE_DEFER from devm_clk_get() call. Let's use core_initcall (qcom and a few other clk drivers use that) for driver registration to avoid those unnecessary -EPROBE_DEFER and get rid of the side effect with ZX296718 display system.
