The dt-bindings header <dt-bindings/clock/qcom,x1p42100-videocc.h> is present in qcom-specific kernel trees (qcom-6.18, qcom-next) but is not yet available in linux-yocto based trees (yocto-6.18, yocto-next). A file-existence check cannot be replaced by a version number because both kernel families share the same version. Add a build-time probe in video/Kbuild that tests for the header using $(shell test -f ...) and, when found, passes -DMSM_VIDC_HAS_X1P42100_VIDEOCC=1 to the compiler. In driver/platform/purwa/src/purwa.c guard the include of that header and the three clock-table entries whose initialiser values (VIDEO_CC_MVS0C_CLK, VIDEO_CC_MVS0_CLK, VIDEO_CC_MVS0_BSE_CLK) are defined exclusively by it with the same macro.

This PR brings up the purwa (X1P42100) platform on the video driver branch. It includes OPP clock table support, hardware power sequence fixes, UBWC global config, and a build compatibility fix to allow promotion across all supported kernel trees.
