Subject: [PATCH v1] arm64: defconfig: mediatek: enable PHY drivers

The mediatek display driver fails to probe on mt8173 and mt8183 in
v6.14-rc4, with the following errors:

mt8173:
platform 1401b000.dsi: deferred probe pending: mtk-dsi: Failed to get hs clock
platform 14025000.hdmi: deferred probe pending: (reason unknown)
i2c 1-0008: deferred probe pending: (reason unknown)

mt8183:
platform 14014000.dsi: deferred probe pending: mtk-dsi: Failed to get hs clock
i2c 4-0058: deferred probe pending: anx7625: fail to find dsi host.

Enabling CONFIG_PHY_MTK_MIPI_DSI=y in drm-ci resolves this error,
but mt8173 still fails with,

[drm:mtk_dsi_host_attach] *ERROR* failed to add dsi_host component: -517
panel-simple-dp-aux aux-1-0008: DP AUX done_probing() can't defer
panel-simple-dp-aux aux-1-0008: probe with driver panel-simple-dp-aux failed with error -22

Enabling CONFIG_PHY_MTK_XSPHY=y and CONFIG_PHY_MTK_HDMI=y in drm-ci
resolves this issue for mt8173.

So enable these PHY configs for mediatek platforms.
