The driver currently only supports R8A7779 SoC. Compared to it, R8A7778 USB-PHY has extra register range containing two high-speed signal quality characteristic control registers which should be set up during USB-PHY startup depending on whether a ferrite bead is in use or not. So, we now handle an optional second memory range in the driver's probe method, add the 'ferrite_bead' field to the driver's platform data, and add an extra (optional) step to the USB-PHY startup routine which sets up the extended registers. Also mark in the driver's Kconfig section that R8A7778 is now supported and generally clarify that section, uppercasing the word "phy" and also changing the module name that got lost in the big driver rename, while at it... The patch has been tested on the Marzen and BOCK-W boards.
