Hello,

This small series prepares the rcar_gen4_ptp to be useable both on both
R-Car S4 and V4H. The only in-tree driver that make use of this is
rswtich on S4. A new Ethernet (R-Car Ethernet TSN) driver for V4H is on
it's way that also will make use of rcar_gen4_ptp functionality.

Patch 1-2 are small improvements to the existing driver. While patch 3-4
adds V4H support. Finally patch 5 turns rcar_gen4_ptp into a separate 
module to allow the gPTP functionality to be shared between the two 
users without having to duplicate the code in each.

See each patch for changelog.
