Change all uses of tristate in the PHY Kconfigs to bool. U-Boot does
not support modules, so tristate does not make sense here.

Add SPL_PHY_CADENCE_TORRENT configuration option to enable the Cadence
Torrent PHY driver in SPL stage. This is required for PCIe boot support
where SERDES configuration must be done early in the boot sequence
before loading the bootloader image over PCIe.

Add a Sierra PHY driver with PCIe and USB support.
This driver is a port from the mainline linux driver.
The PHY has multiple lanes, which can be configured into
groups, and a generic PHY device is created for each group.
There are two resets controlling the overall PHY block, one
to enable the APB interface for programming registers, and
another to enable the PHY itself. Additionally there are
resets for each PHY lane.
The PHY can be configured in hardware to read register
settings from ROM, or they can be written by the driver.
The sequence of operation on startup is to enable the APB
bus, write the PHY registers (if required) for each lane
group, and then enable the PHY. Each group of lanes
can then be individually controlled using the power_on()/
power_off() function for that generic PHY
One difference with the linux driver is that the PHY is
always reset after it is powered-on. This is because role
switching is not supported in u-boot and the cable
orientation is handled by the PHY reset.
