[PATCH v2 2/3] mxs: register clkdev "hbus" as it is required by OCOTP

[Christoph G. Baumann]

From: "Christoph G. Baumann" <cb at sgoc.de>

The OCOTP driver needs to switch the HBUS clock when burning OTP bits.
For this purpose it uses the CLK-API and requests a handler for "hbus".
Trying to burn bits without registered "hbus" CLK results in a blocked user
process.
