[PATCH v4] arm64: defconfig: mediatek: enable PHY drivers

[Vignesh Raman]

The mediatek display driver fails to probe on mt8173-elm-hana and
mt8183-kukui-jacuzzi-juniper-sku16 in v6.14-rc4 due to missing PHY
configurations.

Commit 924d66011f24 ("drm/mediatek: stop selecting foreign drivers")
stopped selecting the MediaTek PHY drivers, requiring them to be
explicitly enabled in defconfig.

Enable the following PHY drivers for MediaTek platforms:
CONFIG_PHY_MTK_HDMI=m for HDMI display
CONFIG_PHY_MTK_MIPI_DSI=m for DSI display
CONFIG_PHY_MTK_DP=m for DP display

Fixes: 924d66011f24 ("drm/mediatek: stop selecting foreign drivers")

v2:
  - Include board details in the commit message.  
  - Sort newly added PHY configs in defconfig.

v3:
  - Use defconfig/savedefconfig to get the correct configs ordering.
  - Removed PHY_MTK_XSPHY since it is not required for probing display driver.
  - Add the commit details which deselected the MediaTek PHY drivers and
    added a Fixes tag.
  - Enabled CONFIG_PHY_MTK_DP, which was previously deselected.

v4:
  - Reword commit message.
