Simon Glass	8729b1ae2c	misc: Update read() and write() methods to return bytes xfered At present these functions return 0 on success. For some devices we want to know how many bytes were transferred. It seems useful to adjust the API to be more like the POSIX read() and write() functions. Update these two methods, a test and all users.

misc: Update read() and write() methods to return bytes xfered

At present these functions return 0 on success. For some devices we want
to know how many bytes were transferred. It seems useful to adjust the API
to be more like the POSIX read() and write() functions.

Update these two methods, a test and all users.

clk: Add support for Arm's Versatile Express OSC clock generators

The Arm Versatile Express and Juno development boards contain an
OSC clock generator that can be accessed through the Versatile
Express config bus. The generators are quite often being controlled
by some MCU and the config bus offers a uniform way of exposing them.
