Commit 0ee6c8a921b1 ("media: qcom: camss: Add support for PHY API
devices") added a call to phy_mipi_dphy_get_default_config_for_hsclk()
in camss-csiphy.c but did not select GENERIC_PHY_MIPI_DPHY, the
invisible bool gating phy-core-mipi-dphy.c where that helper lives.
With CONFIG_VIDEO_QCOM_CAMSS=y and no other driver pulling in
GENERIC_PHY_MIPI_DPHY, the build fails at link time:
camss-csiphy.c:(.text+0x51d): undefined reference to
`phy_mipi_dphy_get_default_config_for_hsclk'
Select GENERIC_PHY_MIPI_DPHY, matching the other MIPI D-PHY consumers
such as rkisp1, mali-c55, cadence-csi2rx and sun6i-mipi-csi2.
Fixes: 0ee6c8a921b1 ("media: qcom: camss: Add support for PHY API devices")

So do we still need to select GENERIC_PHY?

Select GENERIC_PHY_MIPI_DPHY and drop the explicit "select GENERIC_PHY",
which is redundant as GENERIC_PHY_MIPI_DPHY selects GENERIC_PHY
transitively (drivers/phy/Kconfig). This matches the other MIPI D-PHY
consumers such as rkisp1, mali-c55 and sun6i-mipi-csi2.
