Traditionally, we've tracked the parent/child relationships between
clk structures by setting the child's parent member to point at the
upstream clock.  As a result, when decending the tree, we have had
to scan all clocks to find the children.

Avoid this wasteful scanning by keeping a list of the clock's children.

This fixes booting, and is a step toward fixing things properly:

- Make enable_reg u32 instead of u16
  [rmk: virtual addresses are void __iomem *, not u32]
- Get rid of VIRTUAL_IO_ADDRESS for clocks
- Use __raw_read/write instead of omap_read/write for clock registers

This patch adds a bunch of compile warnings until omap1 clock
also uses offsets.

It makes no sense to have the CKCTL rate selection implemented as a flag
and a special exception in the top level set_rate/round_rate methods.
Provide CKCTL set_rate/round_rate methods, and use these for where ever
RATE_CKCTL is used and they're not already overridden.  This allows us
to remove the RATE_CKCTL flag.

... and use it for clocks which are ALWAYS_ENABLED.  These clocks
use a non-NULL enable_reg pointer for other purposes (such as
selecting clock rates.)

Nothing tests the clock flags for this bit, so it serves no purpose.
Remove it.

This will simplify the MMC low-level init, and make it more
flexible to add support for a newer MMC controller in the
following patches.

The patch rearranges platform data and gets rid of slot vs
controller confusion in the old data structures. Also fix
device id numbering in the clock code.

Some code snippets are based on an earlier patch by
Russell King <linux@arm.linux.org.uk>.

Patch from Tony Lindgren

This patch syncs the mainline kernel with linux-omap tree.
The highlights of the patch are:

- Omap1 serial pport and framebuffer init updates by Imre Deak

- Add support for omap310 processor and Palm Tungsten E PDA
  by Laurent Gonzales, Romain Goyet, et al. Omap310 and
  omap1510 processors are now handled as omap15xx.

- Omap1 specific changes to shared omap clock framework
  by Tony Lindgren

- Omap1 specific changes to shared omap pin mux framework
  by Tony Lindgren

- Other misc fixes, such as update memory timings for smc91x,
  omap1 specific device initialization etc.
