There are two parameters, ref_clk and coefficient, for U2 slew rate
calibrate which may vary on different SoCs, here allow them to be
configurable

The default value of mcu_bus_ck_gate_en is 1, if clear it, will
prevent system to enter deep idle mode, so keep its default value
and without affecting PCIe function.

V1 TPHY for SATA doesn't have shared banks if it isn't shared
with PCIe or USB, so make it optional.

When system is running, if usb2 phy is forced to bypass utmi signals,
all PLL will be turned off, and it can't detect device connection
anymore, so replace force mode with auto mode which can bypass utmi
signals automatically if no device attached for normal flow.
But keep the force mode to fix RX sensitivity degradation issue.

This is used to force PHY with USB OTG function to enter a specific
mode, and override OTG IDPIN(or IDDIG) signal.

Chip bank of version-1 is initialized as NULL, but it's used
by pcie_phy_instance_power_on/off(), so assign it a right
address.

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
