openrisc-timer: Reduce overhead, Separate clock update functions

The clock value is only evaluated when really necessary reducing
the overhead of the timer handling.

This also solves a problem in the way the Linux kernel
handles the timer and the expected accuracy....

hw: Clean up bogus default boot order

We set default boot order "cad" in every single machine definition
except "pseries" and "moxiesim", even though very few boards actually
care for boot order, and "cad" makes sense for even fewer.

Machines that care:...

hw/openrisc: Avoid undefined shift in openrisc_pic_cpu_handler()

In C99 signed shift (1 << 31) is undefined behavior, since the result
exceeds INT_MAX. Use 1U instead and move the shift after the check.

hw/openrisc: Fix masking in openrisc_pic_cpu_handler()

Consider the masking of PICSR and PICMR:

((cpu->env.picsr && (1 << i)) && (cpu->env.picmr && (1 << i)))

To correctly mask bits, we should use the bitwise AND "&" rather than
the logical AND "&&". Also, the loop is not necessary for masking....

hw: move headers to include/

Many of these should be cleaned up with proper qdev-/QOM-ification.
Right now there are many catch-all headers in include/hw/ARCH depending
on cpu.h, and this makes it necessary to compile these files per-target.
However, fixing this does not belong in these patches....

cpu: Move halted and interrupt_request fields to CPUState

Both fields are used in VMState, thus need to be moved together.
Explicitly zero them on reset since they were located before
