usb: phy: msm: Select secondary PHY via TCSR
Select the secondary PHY using the TCSR register, if phy-num=1
in the DTS (or phy_number is set in the platform data). The
SOC has 2 PHYs which can be used with the OTG port, and this
code allows configuring the correct one.
Note: This resolves the problem I was seeing where I couldn't
get the USB driver working at all on a dragonboard, from cold
boot. This patch depends on patch 5/14 from Ivan's msm USB
patch set. It does not use DT for the register address, as
there's no evidence that this address changes between SoC
versions.
