phy: phy-mt65xx-usb3: add mediatek directory and rename file
The driver is actually for T-PHY which supports USB3.0, PCIe and SATA, and supports more SoCs now, but not just only for series of mt65xx SoCs, so the name of file, data struct, functions etc with 'mt65xx' may cause misunderstanding when new SoCs are supported. Here rename them to reflect the real functions and also enhance readability. And also update MAINTAINERS file to reflect the correct driver Signed-off-by: Chunfeng Yun <chunfeng.yun@mediatek.com> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>
