779fabf2a0 phy: phy-mtk-mipi-dsi: Remove redundant dev_err call in mtk_mipi_tx_probe() 
There is a error message within devm_ioremap_resource
already, so remove the dev_err call to avoid redundant
error message.

9a8b9434c6 phy: mediatek: Add missing MODULE_DEVICE_TABLE() 
This patch adds the missing MODULE_DEVICE_TABLE definitions on different
Mediatek phy drivers which generates correct modalias for automatic loading
when these drivers are compiled as an external module.

90f80d9599 phy: mediatek: Move mtk_mipi_dsi_phy driver into drivers/phy/mediatek folder 
mtk_mipi_dsi_phy is currently placed inside mediatek drm driver, but it's
more suitable to place a phy driver into phy driver folder, so move
mtk_mipi_dsi_phy driver into phy driver folder.
