Merge tag 'qcom-fixes-2025.04-rc4' of https://source.denx.de/u-boot/custodians/u-boot-snapdragon

CI: https://source.denx.de/u-boot/custodians/u-boot-snapdragon/-/pipelines/24841

The clk_stub, regulator, and pinctrl fixes enable the sdcard on the RB5
dev board (and sm8250 devices broadly). clk_stub is only enabled in
qcom_defconfig and the others are qcom specific so these shouldn't
affect other platforms.

Lastly, a small ufetch fix from Sam which gets color rendering correctly
on U-Boots framebuffer video device.
