Add a driver for the internal Broadcom Kona USB 2.0 PHY found
on the BCM281xx family of SoCs.

Kishon, are you ok with this driver ?

yeah. Since this patch touches phy/Kconfig (and Makefile) and there is one more
PHY driver to be merged that also modifies Kconfig there might be conflicts. So
thought I should be taking this patch?

I think this set_drvdata() should be done before registering the
provider, no ?

hmm, right.

Thanks
