[PATCHv1 2/4] ARM: dts: socfpga: add a bypass-reg binding for Stratix10

[Dinh Nguyen <dinguyen-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org>]

Add a 'bypass-reg' binding property for the Stratix10 clock. There are quite a
few clocks on the Stratix10 platform that have a separate bypass setting from
the clock's original parent.

The 'bypass-reg' binding contains the bypass register offset from the clock
manager's base address and a bit index.
