lk2nd: display: panel: generated: Add hx8394a_720p_video for vivo,pd1410

[zhangzqs]

The vivo-pd1410 device (Vivo Y27L / Y627 / Y927) added in #721 uses the hx8394a_720p_video panel, but the generated panel driver was not included alongside the device node. As a result, the lk1st build command documented in msm8916-vivo-cdp-1.dts for this device fails to link:

make -j$(nproc) TOOLCHAIN_PREFIX=arm-none-eabi- lk1st-msm8916 \
    LK2ND_DISPLAY=hx8394a_720p_video \
    LK2ND_BUNDLE_DTB=msm8916-vivo-cdp-1.dtb \
    LK2ND_COMPATIBLE=vivo,pd1410

undefined reference to `panel_hx8394a_720p_video_select'

lk2nd's oem_panel.c selects the panel via panel_select(LK2ND_DISPLAY), which expands to panel_hx8394a_720p_video_select(). This function is provided by the generated panel header, so the header is required — the gcdb panel_hx8394a_720p_video.h is filtered out by lk2nd/display/panel/rules.mk and does not participate in the build.

This change adds the generated lk_panel_hx8394a_720p_video.h driver and registers it in panels.h.

Verification

Boot-tested on Vivo Y927 (PD1410V). The lk1st build command above now links successfully and produces emmc_appsboot.mbn. The panel command sequences and panel_hx8394a_720p_video_select are confirmed present in the resulting binary.
