[PATCH v2 1/2] clk: imx6q: guard LDB clock init with appropriate video config

[Md Shofiqul Islam <shofiqtest@gmail.com>]

Guard calls to select_ldb_di_clock_source() with the correct video
Kconfig symbol rather than the broad !CONFIG_SPL_BUILD guard.

SPL can support VIDEO, PANEL, and SPLASH_SCREEN so !CONFIG_SPL_BUILD
excluded SPL builds that legitimately need to configure the LDB clocks.

- board/ge/b1x5v2: guard with CONFIG_SPL_VIDEO — LDB init is needed
  in SPL only when display support is enabled
- board/aristainetos: guard with CONFIG_VIDEO_IPUV3 — this board does
  not use SPL so CONFIG_SPL_VIDEO is not the right guard here
- drivers/clk/imx/clk-imx6q: update both the definition of
  imx6q_init_ldb_clks() and its call site to use
  (!CONFIG_SPL_BUILD || CONFIG_SPL_VIDEO) — the function is needed
  in SPL when CONFIG_SPL_VIDEO is set, and on all non-SPL builds
