Realview/Versatile copied the Integrator timer code, including the
calculations for ensuring that the reload value fits into the 16-bit
counter.  However, these platforms have a 32-bit counter which is
clocked at a slower rate.

The result is that the preprocessor conditions are never triggered:
TICKS_PER_uSEC = 1, mSEC_10 = 10000, which is 0x2710 - less than
0x10000.

So, remove the unnecessary complexity, reducing the TIMER_RELOAD
calculation to just:

	TICKS_PER_uSEC * mSEC_10

The only difference between ICST307 and ICST525 are the two arrays
for calculating the S parameter; the code is now identical.  Merge
the two files and kill the duplicated code.

These functions were originally implemented for the CLCD driver before
we had clk API support.  Since the CLCD driver does not use these

This is used by the inode lookup ioctl to follow all the backrefs up
to the subvol root.  But the search being done would sometimes land one
past the last item in the leaf instead of finding the backref.

This changes the search to look for the highest possible backref and hop
back one item.  It also fixes a leaked path on failure to find the root.
